Management of vocal fold scar with autologous fat implantation: perceptual results.

Vocal fold scar disrupts the mucosal wave and interferes with glottic closure. Treatment involves a multidisciplinary approach that includes voice therapy, medical management, and sometimes surgery. We reviewed the records of the first eight patients who underwent autologous fat implantation for vocal fold scar. Information on the etiology of scar, physical findings, and prior interventions were collected. Videotapes of videostroboscopic findings and perceptual voice ratings [Grade, Roughness, Breathiness, Asthenia, Strain (GRBAS)] were randomized and analyzed independently by four blinded observers. Etiology of scar included mass excision (7), vocal fold stripping (3), congenital sulcus (2), and hemorrhage (1). Prior surgical procedures performed included thyroplasty (1), autologous fat injection (9), excision of scar (2), and lysis of adhesions (2). Strobovideolaryngoscopy: Statistically significant improvement was found in glottic closure, mucosal wave, and stiffness (P = 0.05). Perceptual ratings (GRBAS): Statistically significant improvement was found in all five parameters, including overall Grade, Roughness, Breathiness, Asthenia, and Strain (P = 0.05). Patients appear to have improved vocal fold function and quality of voice after autologous fat implantation in the vocal fold. Autologous fat implantation is an important adjunctive procedure in the management of vocal fold scar, and a useful addition to the armamentarium of the experienced phonomicrosurgeon.

Efficacy and tolerability of 1000-4000 mg per day of levetiracetam as add-on therapy in patients with refractory epilepsy.

The aim of this study was to determine the efficacy and tolerability of 1000-4000 mg/day of levetiracetam (LEV, Keppra) as add-on treatment for refractory epilepsy. This was a dose-escalation study of 29 patients with refractory epilepsy. Patients received placebo for 4 weeks (baseline) followed by levetiracetam 1000 and 2000 mg per day each for 2 weeks, and then 3000 and 4000 mg per day each for 4 weeks. Primary efficacy was assessed by seizure frequency (number/week). Tolerability was assessed by adverse events, laboratory parameters, clinical evaluations, and electrocardiogram. All the study periods were completed by 27 of the 29 patients. A substantially lower median seizure frequency was observed at all levetiracetam dosing periods (1000 mg per day, 1.0 seizures per week; 2000 mg per day, 1.5 seizures per week; 3000 mg per day, 1.0 seizures per week; 4000 mg per day, 0.75 seizures per week) compared with the placebo treatment (2.06 seizures per week). In addition, 22-33% of these patients were seizure free during treatment with levetiracetam compared with only 14% with placebo. Levetiracetam was well tolerated. The most common adverse events were somnolence and asthenia; frequency and severity increased with increasing doses of levetiracetam. Levetiracetam in doses from 1000 to 4000 mg per day is effective. Somnolence and asthenia were more frequent with the highest dose, suggesting that 4000 mg per day may be the upper limit in some patients, although individual susceptibility to somnolence was variable.

Terminal cancer. duration and prediction of survival time.

The duration of the terminal period of cancer allows us to determine its prevalence, which is necessary to plan palliative care services. Clinical prediction of survival influences access to palliative care and the healthcare approach to be adopted. The objective of this study was to determine the duration of the terminal period, the prognostic ability of healthcare professionals to predict this terminal period and the factors that can improve the prognostic accuracy. In the island of Mallorca, Spain, we followed 200 cancer patients at the inception of the terminal period. Twenty-one symptoms, quality of life, prognosis and duration of survival were measured. Using a Cox regression model, a predictive survival model was built. Median duration was 59 days; 95% confidence interval (CI)=49-69 days, mean=99 days. The oncologists were accurate in their predictions (+/-1/3 duration) in 25.7% of cases, the nurses in 21.5% of cases and the family physicians in 21.7% of cases. Errors of overestimation occurred 2.86-4.14 times more frequently than underestimation. In the final model, in addition to clinical prognosis (P=0.0094), asthenia (P=0.0257) and the Hebrew Rehabilitation Centre for Aged Quality of Life (HRCA-QL) Index (P=0.0002) were shown to be independent predictors of survival. In this study, the estimated duration of the terminal period was greater than that reported in a series of palliative care programmes, and survival was overestimated. Oncologists could estimate prognosis more accurately if they also take into account asthenia and HRCA-QL Index.

Gabapentin add-on therapy with adaptable dosages in 610 patients with partial epilepsy: an open, observational study. The French Gabapentin Collaborative Group.

The objectives were to evaluate gabapentin add-on therapy in a large population under conditions close to real practice and to determine the therapeutic doses as reached with adaptable dosages. A 6-month multicentre, open-label study, involved addition of gabapentin to pre-existing treatment at the initial dosage of 1200 mg and subsequent adjustment between 900 and 2400 mg/day according to efficacy and tolerability. A study group of 610 adult patients, with partial epilepsy, persistent seizures and a median seizure frequency with a baseline of 7.2 per month were recruited; one-third had less than four seizures per month. Polypharmacy was frequent, with a mean of 2.3 concomitant drugs. After 6 months, 368 patients (62%) continued on gabapentin, at a mean dosage of 1739 mg/day with 44% of responders. On an intention-to-treat basis, median reduction in frequency was 21.2%, and the responder rate was 33.9%. The responder rate increased to 40.7% in the less severe subgroup receiving only one concomitant drug. Seventy-nine patients (13.4%) remained without seizures during the last evaluation period, versus nine (1.5%) during the baseline. Most of them had initially less than four seizures per month. The most frequent adverse effects, somnolence (29.3%), asthenia (14.6%), nausea (7.9%), ataxia (7.7%) and vertigo (7.2%), occurred rapidly after initial titration to 1200 mg/day, and were usually transitory. Weight gain (8.8%) seemed to be related to gabapentin dose. The combination of two recent drugs, vigabatrin and gabapentin, in 190 patients led to similar efficacy levels, with a tendency for more frequent somnolence and asthenia.

Psychosocial value of space simulation for extended spaceflight.

There have been over 60 studies of Earth-bound activities that can be viewed as simulations of manned spaceflight. These analogs have involved Antarctic and Arctic expeditions, submarines and submersible simulators, land-based simulators, and hypodynamia environments. None of these analogs has accounted for all the variables related to extended spaceflight (e.g., microgravity, long-duration, heterogeneous crews), and some of the stimulation conditions have been found to be more representative of space conditions than others. A number of psychosocial factors have emerged from the simulation literature that correspond to important issues that have been reported from space. Psychological factors include sleep disorders, alterations in time sense, transcendent experiences, demographic issues, career motivation, homesickness, and increased perceptual sensitivities. Psychiatric factors include anxiety, depression, psychosis, psychosomatic symptoms, emotional reactions related to mission stage, asthenia, and postflight personality, and marital problems. Finally, interpersonal factors include tension resulting from crew heterogeneity, decreased cohesion over time, need for privacy, and issues involving leadership roles and lines of authority. Since future space missions will usually involve heterogeneous crews working on complicated objectives over long periods of time, these features require further study. Socio-cultural factors affecting confined crews (e.g., language and dialect, cultural differences, gender biases) should be explored in order to minimize tension and sustain performance. Career motivation also needs to be examined for the purpose of improving crew cohesion and preventing subgrouping, scapegoating, and territorial behavior. Periods of monotony and reduced activity should be addressed in order to maintain morale, provide meaningful use of leisure time, and prevent negative consequences of low stimulation, such as asthenia and crew member withdrawal. Leadership roles and lines of authority need to be studied further to understand the factors leading to status leveling, leadership competition, and role confusion. Finally, the relationship between crews and ground personnel should be characterized in order to minimize the displacement of anger and tension to the outside, to counter the effects of inter-group miscommunications, and to develop support strategies that can help to counter in-group/out-group conflicts. Ground-based space simulations still have a role to play in terms of understanding the impact of these factors and ways of dealing with them. In particular, issues involving language, cultural differences, gender biases, career motivation, monotonous conditions, use of free time, leadership, lines of authority, and the relationship between crews and outside monitoring personnel need to be further characterized and examined under controlled conditions. Until such time as these factors can be studied directly in space, simulations provide an opportunity to learn more about these psychosocial issues and to plan ways of minimizing their negative consequences during actual space missions.

Paclitaxel in combination with carboplatin as salvage treatment in refractory small-cell lung cancer (SCLC): a multicenter phase II study.

PURPOSE: The activity and toxicity of paclitaxel plus carboplatin combination in patients with disease progression after initial chemotherapy for small-cell lung cancer (SCLC) was investigated in a multicenter phase II study. PATIENTS AND METHODS: Thirty-two patients (twenty-seven men) with extensive stage refractory SCLC after EP or CAV front-line chemotherapy were treated with paclitaxel 200 mg/m2 on day 1 and carboplatin 6 AUC on day 2 in a four-week schedule. The patients' median age was 60 years and the performance status (WHO) was 0 for 9, 1 for 20 and 2 for 3 patients. All patients were evaluable for toxicity and 29 for response. RESULTS: Complete response was observed in one (3%) and partial response in seven (22%) for an overall response rate of 25% (95% confidence interval (CI): 10%-40%). Seven (22%) patients had stable disease and seventeen (53%) progressive disease. All but one of the responders had been previously treated with EP combination and three of them had failed to respond. The median duration of response and the median TTP were 3 and 5.5 months, respectively. The median overall survival was seven months. Grade 3-4 neutropenia was observed in 12 (37%) patients and in 2 of these it was associated with infection. There were no toxic deaths. Grade 4 anaemia was observed in one (3%) patient and grade 3 thrombocytopenia in three (9.4%). Non-hematologic toxicity was very mild with grade 2-3 asthenia occurring in 10 (25%) patients; asthenia was the reason for treatment discontinuation in 3 patients. CONCLUSIONS: The combination of paclitaxel and carboplatin is a relatively active and well-tolerated regimen as salvage treatment in patients with refractory SCLC.

Phase I/II study of gemcitabine and vinorelbine plus cisplatin in non-small cell lung cancer.

PURPOSE: We determine the maximum tolerated dose (MTD) and efficacy of gemcitabine plus vinorelbine combined with cisplatin in patients with non-small cell lung cancer (NSCLC). PATIENTS AND METHODS: Chemo naive patients with stage IIIA to IV non-small cell lung cancer received outpatient administration of gemcitabine 1,000 mg/m2 and vinorelbine 25 mg/m2 intravenously on days 1 and 8 every 21 days. Doses of gemcitabine and vinorelbine were escalated by 250 mg/m2 and 5 mg/m2, respectively, at each dose level. Cisplatin was administered at a fixed dose of 50 mg/m2 on days 2 and 9. After the MTD was reached, the study was continued as a phase II trial. RESULTS: From January 1998 to March 1999, sixty-five patients were enrolled. The first 38 patients participated in the phase I evaluation. After 130 cycles, the dose-limiting toxicities were neutropenia, stomatitis, asthenia, and hepatotoxicity occurring at the third and fourth dose levels (doses of gemcitabine/vinorelbine of 1,500/25 and 1,000/30 mg/m2). For the subsequent phase II evaluation, 27 additional patients, out of a total of 53, receiving the MTD of gemcitabine and vinorelbine (1000-1250/25 mg/m2) followed (24 hours later) by cisplatin 50 mg/m2. Thirty one (58%) of 53 assessable patients responded. Objective response for patients with stages III and IV disease, respectively, were 65% and 47%. The median time to progression and the overall survival time were 9 months (95% CI: 5-12) and 11 months (95% CI: 9-13), respectively. World Health Organization toxicity > or = grade 3 neutropenia was registered in 28 (54%) of 52 assessable patients (2% with febrile neutropenia), and > or = grade 3 thrombocytopenia in 15 (29%) patients (4% with bleeding). Nausea/vomiting (> or = grade 2) and asthenia (moderate to severe) occurred in 24 (46%) and 14 (27%) patients, respectively. CONCLUSION: Gemcitabine 1,000-1,250 mg/m2 plus vinorelbine 25 mg/m2 on days 1 and 8, followed by cisplatin 50 mg/m2 24 hours later, is safe for outpatient administration and active in patients with NSCLC.

Phase I trials of pemetrexed.

The maximum tolerated dose of the multitargeted antifolate drug pemetrexed is 600 mg/m(2) every 3 weeks in heavily pretreated patients without folic acid supplementation. However, with folic acid supplementation, higher doses have been given without limiting side effects. The dose-limiting toxicities of pemetrexed are neutropenia, asthenia, and thrombocytopenia. Other adverse effects include anemia, anorexia, rash, nausea, vomiting, peripheral edema, diarrhea, mucositis, and reversible elevations of transaminase and creatinine levels. Multiple pemetrexed combination phase I trials have been completed or are underway. Without folic acid supplementation, pemetrexed doses of 400 to 600 mg/m(2)could be safely administered with full therapeutic doses of irinotecan, gemcitabine, cisplatin, carboplatin, oxaliplatin, and 5-fluorouracil. Preliminary data from other ongoing trials (with folic acid and vitamin B(12) supplementation) have similarly shown that pemetrexed doses of at least 400 to 500 mg/m(2) can be safely administered with therapeutic doses of vinorelbine, docetaxel, and paclitaxel. Combination studies of pemetrexed with agents active in breast cancer (doxorubicin, epirubicin, and cyclophosphamide) and chest radiotherapy are also now underway. Adverse effects of these combinations have included neutropenia, anemia, thrombocytopenia, asthenia, vomiting, diarrhea, rash, nausea, anorexia, mucositis, and reversible transaminase elevation. The phase I trials of pemetrexed have consistently shown activity against a broad range of tumor types, including colorectal cancer, pancreatic cancer, breast cancer, non-small cell lung cancer, and mesothelioma. This activity has been noted not only in the combination trials, but when pemetrexed is given as a single agent as well. Pemetrexed is a promising drug. It is active against a broad range of cancers, and it has manageable side effects that seem to be lessened with folic acid and vitamin B(12) supplementation.

Evaluation of toxicity in 22 patients treated with subcutaneous interleukin-2, alpha-interferon with and without chemotherapy.

Biological response modifiers (BRMs) have greatly modified the immunotherapy of tumors. Interleukin-2 (IL-2) has brought about metastasis regression in some cases of malignant tumors, however, when given systemically, it results in high toxicity. More recently, the subcutaneous administration of IL-2 (combined with alpha-interferon, alpha-IFN) seems to be capable of offering the same chances of therapeutic response, but this time with a lower level of toxicity. The Authors report an evaluation of toxicity in 22 patients treated with a combination of IL-2 + alpha-IFN i.m. with or without chemotherapy. The side-effects present in the majority of cases were: fever, diarrhea and asthenia. Approximately 50% of the patients had nausea/vomiting, mucositis, skin rashes, and slight leukopenia. The following side-effects were noted to a much lesser degree, thrombocytopenia, alterations in hepatic and dizziness and cystitis. Only one patient reached 4th degree toxicity, with mucositis, asthenia and skin rash. All the other patients received the treatment without suspensions for toxicity. Biological evaluations will enable us to determine in the future, the cases which can benefit from therapeutic intensification and thus it would seem opportune at this time to use therapy with acceptable toxicity.

Hyperventilation syndrome: a review.

This article has dealt with the psychophysiological phenomenon known as "hyperventilation syndrome." Published research on this syndrome dates back at least a century to Da Costa's classic investigation involving "soldier's heart". Various labels such as "effort syndrome," "anxiety neurosis," "neurocirculatory asthenia," "vasoregulatory asthenia," and "irritable heart," have been employed over the past century to describe this syndrome. The use of different labels to describe this syndrome seems to be inappropriate. While the symptoms associated with these diagnostic labels appear to be remarkably similar, the treatment for the syndrome often differs as a function of the diagnostic label. Symptoms include breathlessness or dyspnea with effort, parathesia, trembling, tachycardia, tetany, carpopedal spasms, and convulsions in the case of a full-blown attack. Hyperventilation, a normal consequence of vigorous exercise and/or high temperatures, can often occur in some individuals for no apparent reason. Hyperventilation, and the resulting physiological changes, are often associated with decrements in psychomotor performance along with increased error rates. The symptoms which characterize the hyperventilation syndrome can be readily produced in certain "types" of individuals within minutes by requiring the individual to overbreathe or through introduction of a CO2 challenge. The symptoms, once produced, can be quickly reversed by placing a paper sack over the subject's head and requiring him/her to rebreathe expired air. Overbreathing and CO2 challenges do not, however, produce full-blown hyperventilatory attacks in most individuals. That is, some individuals or "types" appear to be especially sensitive to the effects of overbreathing and/or CO2 loading.(ABSTRACT TRUNCATED AT 250 WORDS)

Raltitrexed plus oxaliplatin (TOMOX) as first-line chemotherapy for metastatic colorectal cancer. A phase II study of the Italian Group for the Study of Gastrointestinal Tract Carcinomas (GISCAD).

BACKGROUND: To evaluate the safety and efficacy of the novel raltitrexed/oxaliplatin combination (TOMOX) as first-line chemotherapy for patients with advanced colorectal cancer. MATERIALS AND METHODS: Previously untreated patients with metastatic colorectal cancer received raltitrexed 3 mg/m2 plus oxaliplatin 100 mg/m2, both intravenously, on day 1 every 3 weeks. Patients were re-evaluated after every third cycle and chemotherapy was continued up to tolerance or disease progression. RESULTS: Fifty-eight patients from 13 Italian Group for the Study of Gastrointestinal Tract Carcinomas (GISCAD) centers were accrued from September 1999 to November 2000. According to the intention-to-treat analysis from 58 patients, the overall response rate was 50% [95% confidence interval (CI) 38% to 62%], with three complete responses and 26 partial responses. The median overall survival (44 patients currently alive) was >9 months and the median time to disease progression was 6.5 months (range 1-15 months). The main hematological toxicity was grade III/IV neutropenia, which occurred in 17% of patients, while anemia and thrombocytopenia were uncommon. Grade III/IV non-hematological toxicities were transient transaminitis (17% of patients); asthenia (16% of patients); neurotoxicity (10% of patients) and diarrhea (7% of patients). No toxic death was observed, one patient with grade IV asthenia after the first cycle refused chemotherapy. CONCLUSIONS: The results of this study suggest that the TOMOX combination is an effective and well tolerated regimen for the treatment of advanced colorectal cancer. Its ease of administration and patient tolerance warrant further investigation as an alternative to fluoropyrimidine-based regimens with repeated and prolonged fluorouracil infusions.

A dose-escalation and pharmacokinetic study of gemcitabine and oxaliplatin in patients with advanced solid tumors.

BACKGROUND: Gemcitabine and oxaliplatin have broad antineoplastic activity and favorable toxicity. We conducted a phase I study to determine the maximum tolerated doses (MTDs) and dose-limiting toxicities (DLTs) of the combination in patients with advanced solid tumors. PATIENTS AND METHODS: Sixty-eight patients with advanced stage solid tumors were enrolled. Treatment was first-line for 35% of patients, second-line for 27%, and third-line for 38%. Gemcitabine was administered at escalating doses of 1000-2000 mg/m(2) as a 30-min intravenous (i.v.) infusion on days 1 and 8 and oxaliplatin at 60-130 mg/m(2) as a 4-h i.v. infusion on day 8 every 21 days without growth factor support. RESULTS: The MTD was defined at gemcitabine 1800 mg/m(2) on days 1 and 8 and oxaliplatin 130 mg/m(2) on day 8. Twelve dose levels were evaluated and DLTs occurring during the first cycle consisted of grade 4 neutropenia, grade 3 asthenia or mucositis and grade 1-3 neutropenia or thrombocytopenia resulting in treatment delays. A total of 266 cycles were administered with only one episode of febrile neutropenia and no toxic deaths. Seven (3%) and 26 (10%) cycles were complicated by grade 4 and 3 neutropenia, respectively, three (1%) and 13 (5%) by grade 4 and 3 thrombocytopenia, and eight (3%) by grade 3 anemia. The most common non-hematological toxicity was grade 2/3 asthenia observed in 23% of cycles. Responses were observed in patients with a variety of epithelial neoplasms. The pharmacokinetic study revealed no significant interaction between the two drugs. CONCLUSIONS: The combination of gemcitabine and oxaliplatin has excellent tolerability and promising activity in patients with advanced solid tumors. As the MTD exceeds the recommended single-agent dose for gemcitabine, and a dose-response effect has not been established, we recommend using both drugs at full doses, e.g. gemcitabine 1200-1400 mg/m(2) on days 1 and 8 and oxaliplatin 130 mg/m(2) on day 8 for further phase II studies.

Biweekly vinorelbine and gemcitabine: a phase I dose-finding study in patients with advanced solid tumors.

BACKGROUND: The purpose of this study was to determine the dose-limiting toxicity (DLT) and maximum tolerated dose of a combination of vinorelbine plus gemcitabine administered on a biweekly schedule in patients with advanced solid tumors. PATIENTS AND METHODS: Patients with advanced or refractory solid tumors included in this phase I study were treated with vinorelbine followed by gemcitabine. Vinorelbine was given intravenously over 10 min, and gemcitabine was given intravenously at an fixed-dose infusion rate of 10 mg/m(2)/min. Six dose levels of vinorelbine/gemcitabine were explored: 20/2000, 25/2500, 25/3000, 30/3000, 30/3500 and 30/2500 mg/m(2). RESULTS: Nineteen patients were included in the study. Fourteen patients were pretreated with chemotherapy and/or radiotherapy. A total of 123 cycles of chemotherapy were administered. DLTs were neutropenic fever and grade 3 asthenia at dose level 5 (30/3500 mg/m(2)); at dose level 4 (30/3000 mg/m(2)) they were grade 3 asthenia, and a radiation-recall reaction and pneumonitis. Sixteen patients were evaluable for efficacy. Five patients had an objective response (one complete response and four partial responses), for an overall response rate of 31%. CONCLUSIONS: The recommended dose for phase II study is vinorelbine 30 mg/m(2) and gemcitabine 2500 mg/m(2) administered once every 2 weeks. This regimen is feasible and well-tolerated at this dose, and shows a good clinical activity in all levels explored.

Combination therapy with gefitinib, an epidermal growth factor receptor tyrosine kinase inhibitor, gemcitabine and cisplatin in patients with advanced solid tumors.

BACKGROUND: The aim of this study was to investigate the tolerability, pharmacokinetic interaction and antitumor activity of gefitinib ("Iressa", ZD1839), an orally active, selective epidermal growth factor receptor tyrosine kinase inhibitor, combined with gemcitabine and cisplatin in chemotherapy-naïve patients with advanced solid tumors. PATIENTS AND METHODS: This was an open-label feasibility trial evaluating two doses of gefitinib (250 and 500 mg/day) in combination with gemcitabine and cisplatin. Gefitinib was administered daily from day 2 onwards. Gemcitabine 1250 mg/m(2) was given on days 1 and 8 and cisplatin 80 mg/m(2) on day 1 for up to six 3-week cycles. Patients could then continue to receive gefitinib monotherapy. RESULTS: Eighteen patients were entered, nine at each gefitinib dose level. Two patients developed dose-limiting toxicity: one grade 3 convulsion (250 mg/day dose group) and one grade 3 rash (500 mg/day dose group). The most frequently occurring adverse events in the combination phase were vomiting (17 patients), asthenia (16), nausea (14), diarrhea (14) and skin rash (13). The most common grade 3/4 adverse events were vomiting (seven patients), asthenia (six), thrombocytopenia (six), diarrhea (five) and anorexia (five). Pharmacokinetic analyses showed no apparent pharmacokinetic interaction between gefitinib and cisplatin or gemcitabine, with the exception of a possible small increase in the geometric mean exposure to gemcitabine seen on day 8 of therapy when given alone with the higher dose of gefitinib. Of 17 evaluable patients, nine had confirmed partial responses, seven had stable disease and one had progressive disease. CONCLUSIONS: Combination therapy of gefitinib with cisplatin and gemcitabine had a manageable and predictable safety profile, no major effect on exposure to any of the three drugs and antitumor activity.

Epirubicin--docetaxel combination in first-line chemotherapy for patients with metastatic breast cancer: final results of a dose-finding and efficacy study.

The aim of the study was to define a regular and tolerable dose of the epirubicin-docetaxel combination in first-line chemotherapy of patients with metastatic breast cancer. Sixty-five women with measurable and/or evaluable disease were treated with epirubicin escalated from 60 to 110 mg/m(2) according to 5 dose levels, in combination with a fixed dose of 75 mg/m(2) docetaxel, every 21 days for 6 cycles, without preventive use of hematopoietic growth factors or antibiotics. Forty-three women received adjuvant chemotherapy, consisting of anthracyline- or anthracenedione-based regimens in 39 cases (60%). Twenty-seven women were treated in the phase I study (3 at epirubicin 60 mg/m(2), and 6 at each subsequent dose level). Dose-limiting toxicity consisted of grade III asthenia and febrile neutropenia (epirubicin 75 mg/m(2)), grade IV thrombopenia and grade III asthenia (epirubicin 90 mg/m(2)), grade IV stomatitis and grade III diarrhea (epirubicin 100 mg/m(2)), and grade III diarrhea (epirubicin 110 mg/m(2)). In the phase II study, an additional 38 women were treated at epirubicin 90 mg/m(2) and epirubicin 100 mg/m(2). During the 349 cycles delivered, grade IV neutropenia occurred in 90%; febrile neutropenia requiring hospitalization occurred in 62 (17.8%) and lasted more than 3 days in 12 (3.4%). Nonhematologic toxicity was acceptable. Three left ventricular ejection fraction depressions occurred and normalized during follow-up. The overall response rate in the 62 evaluable women was 69.4% (range: 58--81%), with a median duration of 7.8 months. After 26 months of follow-up, the median time to progression was 9.1 months and median overall survival was 22.7 months. On the basis of efficacy and toxicity, the recommended dose of the combination is epirubicin 100 mg/m(2) plus docetaxel 75 mg/m(2).

A phase II trial of docetaxel in advanced non-small cell lung cancer.

Twenty-nine patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) were treated with docetaxel. Ten patients had already received chemotherapy, the others had received no chemotherapy. Docetaxel was administrated i.v. over 60 min every 21 days at a dose of 100 mg/m2. Twenty-three patients were evaluable for response. There were no complete responses and eight partial responses. The overall response rate was 35% (28% in the intent to treat analysis). Median duration of response was 43 weeks and median time to progression 12 weeks. Neutropenic infections, neurotoxicity and asthenia were dose-limiting toxicities (6% of 118 cycles). The other main toxicities were asthenia in 48%, skin reactions in 31% and nail changes in 31% of the patients. Single-agent docetaxel appears to be active against both previously treated and untreated advanced NSCLC. Toxicity was acceptable but should be carefully monitored.

Acoustic and perceptual evaluation of laryngeal reinnervation by ansa cervicalis transfer.

OBJECTIVES/HYPOTHESIS: To evaluate the acoustic and perceptual results of laryngeal reinnervation with ansa cervicalis to recurrent laryngeal nerve anastomosis. STUDY DESIGN: Retrospective study of voice samples from 12 patients with unilateral recurrent laryngeal nerve paralysis, treated with ansa cervicalis to recurrent laryngeal nerve anastomosis. Samples were recorded before surgery and at least 8 months after surgery. METHODS: The samples were subjected to several acoustic analyses sensitive to paralytic dysphonia, including cepstral peak prominence, noise-to-harmonics ratio, and measures of frequency and amplitude perturbation. The voice samples from the patients were randomized with age- and sex-matched samples from normal subjects and judged by trained listeners for overall dysphonia, roughness, breathiness, asthenia, and strain. The preoperative and postoperative results were compared statistically, and the postoperative results were compared with the matched normal subjects. RESULTS: As a group, the patients showed improvement (P < .05) in cepstral peak prominence, frequency perturbation, and perceptual judgments of overall dysphonia, breathiness, and asthenia. The best results occurred in patients with isolated vocal fold paralysis. The postoperative group as a whole did not improve to the level seen in matched normals. Suboptimal results were seen primarily in patients with untreated laryngeal or extralaryngeal pathology beyond the laryngeal paralysis. CONCLUSIONS: These data suggest that laryngeal reinnervation has the potential to bring about a return to normal or near-normal voice in patients with isolated unilateral vocal fold paralysis.

Do early symptoms of pancreatic cancer exist that can allow an earlier diagnosis?

Diagnosis of pancreatic cancer is made late, and prognosis remains extremely poor. This study was carried out to investigate whether symptoms exist before pain or jaundice that could suggest pancreatic cancer and favor earlier diagnosis. The study involved 305 patients with confirmed pancreatic cancer and 305 controls. All subjects were interviewed personally at least twice about their clinical history; pancreatic cancer patients were asked about any disturbances before abdominal pain or jaundice. Of the 305 pancreatic cancer patients, 151 (49.5%) had some prior disturbances, 108 (35.4%) 6 months or less before pain or jaundice and 43 (14.1%) more than 6 months before. Among the latter, 14 (4.6% of all patients) had had anorexia and/or early satiety and/or asthenia (7-20 months before pain or jaundice), 11 (3.6%) had disgust for coffee and/or smoking and/or wine (7-20 months before), 14 (4.6%) had diabetes (7-24 months before), and four (1.3%) had acute pancreatitis (8-26 months before). Among the controls, the only reports of these symptoms were two (0.7%) cases of asthenia (4 and 6 years earlier), 22 (7.2%) cases of diabetes (of which only two [0.7%] were diagnosed 7-24 months before the interview), and one (0.33%) case of acute pancreatitis (10 years earlier). Apart from acute pancreatitis, all the other differences between patients and controls were statistically significant. In approximately 15% of patients, disturbances existed more than 6 months before pain or jaundice, which, although not specific, could raise suspicion of the possibility of pancreatic cancer. These disturbances could represent the one current opportunity for an earlier diagnosis in a significant minority of pancreatic cancer patients.
