Post-operative adjuvant chemotherapy for colorectal cancer with 5-fluorouracil (5-FU) infusion combined with 1-hexylcarbamoyl-5-fluorouracil (HCFU) oral administration after curative resection.

BACKGROUND: Although surgical resectability is an important prognostic factor, recurrences are commonly noted in advanced colorectal cancer patients, even after apparently curative surgery. Since such recurrences cannot be cured, better adjuvant chemotherapies are urgently required. PATIENTS AND METHODS: We studied the effect of post-operative chemotherapy using oral administration of 1-hexylcarbamoyl-5-fluorouracil (HCFU) with 5-fluorouracil (5-FU) infusion for curatively-resected Stage IIIa and IIIb colorectal cancers. This study was prospectively randomized and controlled and 314 (97.8%) out of 321 patients were determined to be candidates for statistical assessment. Group A and Group B received 5-FU intravenous injection at, respectively, 333 mg/m2 and 1000 mg/m2 body surface area/24 hours continuously for 72 hours beginning on post-operative day 0 and day 6, with oral HCFU 300 mg daily for 52 weeks beginning 2 weeks after surgery. RESULTS: There were no differences in overall 5-year survival or disease-free survival between Group A and Group B. A retrospective subset analysis. however, suggested that the protocol of Group B tended to yield better 5-year survival (68.3%) for rectal cancer than that of Group A (58.8%). CONCLUSION: Inductive therapy with high-dose 5-FU in combination with oral HCFU appears to be beneficial as adjuvant chemotherapy for advanced rectal cancer with lymph node metastasis.

[Evaluation clinical long-term curative effect and analysis of its influence factors after restoration of teeth with wedge-shaped defects].

OBJECTIVE: To evaluate the long-term curative effect clinically and analysis of its influence factors after restoration of teeth with wedge-shaped defects. METHODS: Seventy five cases of 509 teeth with various degrees of dental wedge-shaped defects were randomly divided into two groups--the group restored by Dyract Cement and the group restored by 3M-Vitremer. Evaluation was made with the modified USPHS evaluation criterion after restoration for 1,2,4 years respectively. RESULTS: The successful rate dropped down from 2 year successful rate 85.5% to 4-year 27.7%. The new wedge-shaped defects were presented at the cervical margin of the original restoration in 1.8% (2 years later) and 6.6% (4 years later). There were a lot of influence factors on long-term curative effect. The failure rate in the group with occlusal interference was significantly higher than that without occlusal interference. CONCLUSIONS: The clinical successful rates are affected by the value of occlusal force on the restored teeth and the physical properties of the restorative materials. It is suggested that the process of restoration of dental wedge-shaped defect should include obviating occlusal factors as well as to improve the properties of restorative materials.

[Curative effect of percutaneous microwave coagulation therapy for hepatocellular carcinoma].

OBJECTIVE: To observe the curative effect of percutaneous microwave coagulation therapy (PMCT) with 2450 MHz microwave antenna for hepatocellular carcinoma. METHODS: Under local or epidural anesthesia, a thin percutaneous microwave antenna was introduced with ultrasound guidance into the tumor in the liver for thermo-coagulation. RESULTS: Among the 97 hepatic cancer lesions in 52 patients, 61(62.9%) with phi < 3 cm were coagulated once. In follow-up of 6-12 months of these lesions, 57(93.4%) showed no recurrence by CT or MRI. Thirty-six (37.1%) with 3 cm < phi < 5 cm coagulated twice showed that 27 (75.0%) gave CR and 9 (25.0%) gave PR by CT or MRI in follow up of 6 months. There were no serious clinical side effects or complications in the PMCT patients. CONCLUSION: Percutaneous microwave coagulation therapy gives good curative effect on liver tumor with phi < 3 cm. It is partly effective on lesions 3 cm < phi < 5 cm.

Results of curative therapy for esophageal cancer in a community training hospital.

A 12-year experience of therapy for esophageal carcinoma in a community-based cancer center was reviewed retrospectively. Of a total of 88 patients with histologically proven carcinoma of the esophagus 30 (34.1%) underwent curative esophagectomy. Twelve patients received preoperative chemoradiotherapy. Fourteen esophagectomies were performed transhiatally and 16 via the thoracolaparotomy approach. The average distance from incisors was 32.2 and 32.1 cm, respectively. Overall morbidity was 36.7%, with major complications in 30% of patients. Mortality was 3.3%. A comparison of patients treated with preoperative chemoradiotherapy (12 patients) and surgery alone (18 patients) showed no statistical difference in morbidity, mortality, or length of hospital stay. Analysis of these parameters in groups of patients operated via the transhiatal versus thoracolaparotomy approach demonstrated statistically lower morbidity (14.3% versus 56.3%, respectively), with no difference in mortality and a trend toward a shorter hospital stay in the former group. Overall survival at 3 years was 63.9%. In the combined therapy group, 90.9% of patients survived 3 years compared to 40.4% in the surgery only group (P = 0.0177). There was a trend toward better survival in the group of patients treated via the transhiatal approach. This study demonstrated that curative therapy for esophageal carcinoma can be performed with acceptable morbidity and mortality in a community teaching hospital.

Non-curated distributed databases for experimental data and models in neuroscience.

Neuroscience is generating vast amounts of highly diverse data which is of potential interest to researchers beyond the laboratories in which it is collected. In particular, quantitative neuroanatomical data is relevant to a wide variety of areas, including studies of development, aging, pathology and in biophysically oriented computational modelling. Moreover, the relatively discrete and well-defined nature of the data make it an ideal application for developing systems designed to facilitate data archiving, sharing and reuse. At present, the only widely used forms of dissemination are figures and tables in published papers which suffer from inaccessibility and the loss of machine readability. They may also present only an averaged or otherwise selected subset of the available data. Numerous database projects are in progress to address these shortcomings. They employ a variety of architectures and philosophies, each with its own merits and disadvantages. One axis on which they may be distinguished is the degree of top-down control, or curation, involved in data entry. Here we consider one extreme of this scale in which there is no curation, minimal standardization and a wide degree of freedom in the form of records used to document data. Such a scheme has advantages in the ease of database creation and in the equitable assignment of perceived intellectual property by keeping the control of data in the hands of the experts who collected it. It does, however, require a more sophisticated infrastructure than conventional databases since the software must be capable of organizing diverse and differently documented data sets in an effective way. Several components of a software system to provide this infrastructure are now in place. Examples are presented, showing how these tools can be used to archive and publish neuronal morphology data, and how they can give an integrated view of data stored at many different sites.

[Whether or not to treat pneumonia curatively in (demented) psychogeriatric patients: evaluation of a guideline for nursing home physicians].

A guideline was developed to support decision-making about whether or not to treat pneumonia curatively in psychogeriatric (demented) nursing home patients. This guideline was developed as a 'checklist of considerations', primarily of the ethical and legal aspects of decision-making. Nursing home physicians used and evaluated the list. The list's acceptance was assessed by measuring the frequency of the list's use, and judgements of the list's contents and 'usefulness'. The list was used in 50 out of 58 participating nursing homes, in 47% of the 489 psychogeriatric patients in whom pneumonia occurred. The list was found somewhat to very useful to support decision-making in 47% of 107 individual patients. For the targeted patient category as a whole, 85% of 48 physicians who were asked retrospectively (one physician per home) found the list somewhat to very useful. The content of the list was judged favourably. In conclusion, the nursing home physicians accepted the considerations of the checklist as a basis for decision-making on whether or not to treat pneumonia curatively in psychogeriatric patients. In the future, the format of the list can be adapted for use in diverse clinical situations. Suggestions are provided to increase user friendliness and usefulness.

[A report of two cases in which radiation therapy was effective for distant lymph node metastases after curative resection of gastric cancer].

Long-term survival is difficult after manifestation of distant lymph node metastasis following curative resection for advanced gastric cancer. Two patients who achieved long survival with linac therapy after curative treatment of gastric cancer, are reported. Case 1: 45 years old, male. Distal gastrectomy with D2 dissection was carried out for such gastric cancer as L.M, less.Post.Ant, fType 3, T2 (MP), fStage II, on July 13, 1994. As paraaortic lymph nodes metastases was observed with CT examination on October 12, 1995, irradiation therapy using linac was conducted, and CR was achieved. Though Virchow's lymph nodes metastases was followed that episode, PR was achieved with 4,750 cGy of linac therapy. Finally, however, the patient died with metastases to lung and bone on May 19, 2002. Case 2: 62 years old, male. Distal gastrectomy with D2 + No.8p and also No.16b1 interaorticocaval dissection was conducted for such advanced gastric cancers as M, less, fType 3, T3 (SE), fStage III B on June 7, 1995. Paraaortic lymph nodes metastases were observed through CT examination on October 12, 1995. Irradiation therapy using linac resulted in CR. Virchows lymph node metastasis, which appeared on December 12, 1997, was also treated with 5,000 cGy of linac, and CR was also achieved. The patient is surviving today without recurrence.

[Analysis of the late curative effect of 432 cases with advanced squamous cell carcinoma of the maxillary sinus].

OBJECTIVE: To study the late curative effect of different methods used in the treatment of advanced squamous cell carcinoma of the maxillary sinus (SCMS). METHODS: A retrospective analysis of 432 cases with SCMS was done. Among them, 141 cases were in stage III, 291 in stage IV, 244 were male, 188 were female, and the age ranged from 14 to 87 years. Radiotherapy, operation only and the combined treatment (radiation plus operation) were adopted. RESULTS: The 5-year survival rates were 15.6% in radiation group, 21.7% in operation group, and 40.1% in combined group (40% in the preoperative irradiation group, and 43% in the postoperative irradiation group). The 5-year survival rates were 31.7%, 46.6% and 20% respectively for those involving structures above, below or both above and below the Ohngren line. Among the 238 cases with poor curative effect, 198 had local recurrence. CONCLUSION: Combined treatment was the best choice for advanced SCMS. There were no significant differences in the survival rates between preoperative and postoperative radiotherapy groups. The survival rate might be improved by preoperative radiotherapy with a dose of 50 Gy, or postoperative radiotherapy with doses of 60-70 Gy. The prognosis for those with the tumor located below the Ohngren line was much better than those above the line and those both above and below the line. The key to the successful treatment for maxillary sinus carcinoma is to control the local recurrence effectively.

Amifostine and curative intent chemoradiation for compromised cancer patients.

Concurrent chemotherapy and radiation are usually indicated for locally advanced carcinomas such as head and neck and anal malignancies. Because of the toxicity of the treatment, patient selection plays an important role in recommendations to treat with a curative intent. Elderly patients (> 70 years), those with underlying medical conditions or acquired immunological disorders (AIDS) are commonly excluded from combined modality therapy because of their perceived inability to tolerate the aggressive treatment. They may thus be deprived of a potentially curative therapy. In an attempt to improve outcome, we conducted a pilot study using amifostine, a radioprotector, to increase the tolerance of such compromised individuals to treatment. Amifostine (500 mg intravenously) was given during chemotherapy on days 1-5, and days 21-25 of radiation regimen. All patients were able to complete the chemoradiation. Despite the locally advanced stage of the disease, five out of our six patients achieved a complete response (CR). One patient with synchronous primaries had a complete response for the base of tongue cancer and regression of the esophageal cancer, which allowed him to resume oral feeding. All patients achieved improved quality of life. Successful chemoradiation appears to be feasible in patients with advanced stage, age and/or underlying medical conditions when amifostine is integrated in the treatment.

Blood transfusions and results after curative resection for gastric cancer.

On the basis of an analysis of our experience and a review of the literature, this report discusses the effects of perioperative blood transfusions on postoperative morbidity, mortality and 5-year survival in a series of patients who underwent curative surgical treatment of gastric cancer. The authors analyze a consecutive series of 137 patients who underwent curative total or subtotal gastrectomy D2 or D3. Ninety-nine patients (72.2%) received perioperative transfusions. The data examined included the number and timing of transfusions (pre-, intra-, or postoperative), the type of operation (total or subtotal gastrectomy with or without splenectomy), tumor stage (pTNM), and the correlation between transfusions, mortality, morbidity and survival. Advanced T-stage (P = 0.01) and total gastrectomy (P = 0.009) were associated with a higher transfusion rate. No cases of operative mortality were recorded after 1988. Specific morbidity was 10.5% in non-transfused patients and 20.1% in transfused. Five-year survival rate in the transfused patients (28.3%) was significantly lower than in the non-transfused group (53.5%) (P = 0.03). Univariate analysis showed that T-stage (P = 0.001) and N-stage (P = 0.04) were associated with a lower survival. By multivariate analysis (Cox regression model) only T-stage (P = 0.001) and N-stage (P = 0.04) were independent prognostic factors, whereas transfusions were not an independent variable (P = 0.27). To conclude, the issue of the real impact of transfusions on the prognosis of gastric cancer is far from being settled, although the T and N parameters are known to be strictly correlated to prognosis. This study further confirms the importance of limiting homologous transfusions as well as of transfusing, whenever possible, autologous or leukodepleted blood; this, however, without losing sight of the primary goal of minimizing operative blood loss.

[Evaluation of the results of the curative treatment of varices using 3 scoring systems: clinical, Doppler and echographic].

There have been many studies reporting results of curative treatment of varicose veins. Four methodological errors are nevertheless often committed: groups of varicose vein patients not comparable with regard to the degree of venous dilatation; insufficient objective parameters; population inadequately followed up; retrospective studies. It was felt necessary to develop systems for the quantification of varicose disease. These systems provide three grades: a clinical grade, a Doppler grade and an ultrasonographic grade. Clinical grade essentially involves the maximum diameter of varicose veins found by palpation and expressed in millimetres. The Doppler grade takes into account the maximum duration of the reflux wave in compression-decompression manoeuvres. The ultrasonographic grade also involves the maximum diameter of the varicose system. These grades enable the numerical assessment of the results of curative treatment of varicose veins, as well as forming the basis for statistically satisfactory epidemiological surveys.

Carcinoma of the body and tail of the pancreas: is curative resection justified?

BACKGROUND: The role of resection in the treatment of carcinoma of the distal pancreas remains unclear. The less frequent occurrence of tumor in the distal gland, advanced tumor stage at diagnosis, and a lack of reported success have combined to produce therapeutic nihilism in the minds of many surgeons. The goal of this review was to assess long-term survival after distal pancreatectomy for carcinoma of the pancreas. METHODS: The records of all patients undergoing distal pancreatectomy at the Mayo Clinic for a primary pancreatic malignant tumor during the 25-year period from 1963 to 1987 were reviewed. Forty-four patients undergoing potentially curative distal pancreatectomies were identified: 26 patients for ductal adenocarcinoma, 12 patients for islet cell carcinoma, and six patients for cystadenocarcinoma. RESULTS: Major postoperative morbidity occurred in 9% of the patients and operative death in 2% of the patients. Patients with ductal adenocarcinoma frequently were admitted with advanced disease (stage II or III). The median overall survival for patients with ductal adenocarcinoma was 10 months. Fifteen percent of the patients survived 2 years after operation, and 8% of the patients survived 5 years. In contrast, the 5-year survival after resection of islet cell carcinomas and cystadenocarcinomas was excellent (83% and 100%, respectively). CONCLUSION: The prognosis for patients with ductal adenocarcinoma in the distal pancreas who were treated with potentially curative distal pancreatectomy is poor; however, the results are not substantially different from those reported after pancreaticoduodenectomy for malignant tumors of the proximal pancreas. Some patients with adenocarcinoma of the distal pancreas who were treated with resection may be long-term survivors. We recommend resection of carcinoma of the distal pancreas when the disease is limited to the gland and believe that all patients with ductal adenocarcinoma should be considered for postoperative adjuvant radiation and chemotherapy.

Results of radiotherapy with curative intent in non-small cell lung cancer. An analysis of 130 patients.

Between 1970 and 1985, 130 patients were irradiated with curative intent at the Center of Oncology in Kraków. The histological diagnosis was squamous-cell carcinoma in 60.8% of patients, adenocarcinoma in 25.4% of patients and other non-small cell cancer in 13.8% of patients. Out of 130 irradiated patients 21.5% refused surgery, 26.2% were inoperable for medical reasons, and 52.3% had unresectable tumors. According to the UICC TNM 1987 classification, 62 (47.7%) patients had early (stages I and II) disease. The remaining 68 (52.3%) patients had stage III A cancer. Additional criteria for patients selection to radiotherapy with curative intent were: Karnofsky performance status > or = 50, and no respiratory insufficiency. All patients were treated with megavoltage radiation. Patients with stage I were treated by three isocentric beams. Tumor dose was 6000 cGy in 24 fractions over five weeks. In patients with stage II and III A disease the radiotherapy was started with two parallel opposed beams encompassing primary lesion and mediastinum. The dose of 4000 cGy was given in 20 fractions over four weeks, followed by a "boost" dose of 2000 cGy in the fractions over two weeks, delivered with three isocentric beams. 54% of patients were disease-free at the twelfth month, 24.6% at the 36th month, and 18.5% of patients survived five years without evidence of cancer. A significantly better survival has been observed in patients with stages I and II, with Karnofsky performance status > or = 70, and with complete radiological regression eight weeks after radiation therapy. The main cause of failure of the treatment were distant metastases.
