Toxicity and therapeutic response to chemotherapy in patients aged 70 years or older with advanced cancer.

To evaluate the impact of chemotherapy in terms of feasibility and activity in elderly patients, we treated 120 patients aged 70 years or older with advanced cancer in six major organ sites (breast, colorectum, lung, stomach, ovary, and head and neck). Furthermore, we compared the results in this age group with those in 120 patients with similar clinical features receiving the same chemotherapeutic combinations but whose age was under 70. Our results show that chemotherapeutic regimens routinely used in younger patients yield the same benefits and levels of toxicity in older patients. In none of the different organ sites, in fact, did we observe a higher incidence or severity of side effects, nor were there differences in response rate and survival. In conclusion, elderly cancer patients who are not suffering from medical complications, which are generally increased in aged patients (e.g., cardiovascular, pulmonary, renal, or neurological diseases), can be considered candidates for full doses of chemotherapy, like their younger counterparts.

Different doses of granulocyte colony stimulating factor to support a weekly chemotherapeutic regimen in advanced gastric cancer: a randomized study.

It was our intention to verify if increases of granulocyte colony stimulating factor (G-CSF) dose were able to reduce treatment delays due to leukopenia in our weekly regimen of cisplatin (40 mg/m2), epidoxorubicin (35 mg/m2), 6S-leucovorin (250 mg/m2) and 5-fluorouracil (500 mg/m2), usually supported by G-CSF at a dose of 5 mu g/kg. Forty five patients with advanced gastric carcinoma (30 males and 15 females; median age 64 years) were randomized to receive three different doses of G-CSF (5, 8 and 10 mu g/kg) by s.c. injection. We did not observe any difference in the mean value of neutrophil counts at each of the 8 weeks of treatment; while we registered a higher incidence of severe neutropenia (< 500/mm3) in patients receiving higher G-CSF doses: two patients in the group at 5 mu g/kg, four in the group at 8 mu g/kg and seven in the group at 10 mu g/kg. Furthermore, low doses of G-CSF allowed a similar number of chemotherapeutic administrations in the eight study weeks. The results arising from our study do not seem to support the use of higher doses of G-CSF, at least in not such a weekly regimen.

A phase I trial of 5-fluorouracil, leucovorin and interferon-alpha 2b administered by 24 h infusion in metastatic colorectal carcinoma.

A phase I trial of 5-fluorouracil (5-FU), leucovorin (LV) and interferon (IFN) was conducted in 15 advanced colorectal cancer patients refractory to a bolus regimen of 5-FU/LV. Therapy consisted of a weekly i.v. infusion of 5-FU at 2600 mg/m2 administered concomitantly with LV at 500 mg/m2 over a 24 h period. IFN-alpha 2b was administered by 24 h infusion from the second cycle at escalating dose (4.5, 9, 18 and 27 MU/m2). The maximum tolerated dose of IFN was 18 MU/m2. At 27 MU/m2 two patients complained of diarrhea grade 3, so that the escalation of IFN dose was stopped. Two patients achieved a partial response (IFN level dose 9-18 MU/m2). Eight patients had stable disease. Pharmacokinetics of 5-FU were not influenced by IFN at any level dose. Our results show that doses of IFN of 18 MU/m2 given by a 24 h infusion can be administered safely to an established and active schedule of weekly 24 h infusion of 5-FU and LV. A phase II study has been planned to define the level of activity of this regimen.

Have enteric infections a role in 5-fluorouracil-associated diarrhea?

In 16 advanced colorectal cancer patients with 5-fluorouracil-associated diarrhea, we evaluated the role of bacterial pathogens in the development of this adverse effect. Neither Clostridium difficile nor other pathogens were cultured from fecal specimens. These data seem to suggest that it is unlikely that intestinal infections have a role in the pathogenesis of 5FU-associated diarrhea.

A randomised trial of octreotide vs best supportive care only in advanced gastrointestinal cancer patients refractory to chemotherapy.

Octreotide, a somatostatin analogue, has been shown to inhibit the growth of gastrointestinal cancers in vitro and in vivo. To assess the anti-tumour effect of octreotide, we performed a randomised trial comparing octreotide with best supportive care in advanced gastrointestinal cancer patients refractory to chemotherapy. A total of 107 patients with advanced gastrointestinal cancer refractory to chemotherapy were randomised to receive octreotide at the dose of 200 micrograms three times a day for 5 days a week, or the best supportive care only. The primary outcome variable was the survival duration. Response rate was an outcome variable of secondary importance. Fifty-five patients (15 stomach, 16 pancreas, 24 colon-rectum) received octreotide, while 52 (14 stomach, 16 pancreas, 22 colon-rectum) received the best supportive care. Patients treated with octreotide had a significant advantage in duration of survival with a median survival time of 20 weeks vs 11 in the control group (P < 0.0001). This advantage was present also considering the survival data for each tumour group. Twenty-five patients (45%) given octreotide showed stable disease vs only eight (15%) in the control group (P < 0.001). In conclusion, octreotide therapy seems to confer a survival benefit in advanced gastrointestinal cancer patients refractory to chemotherapy. Additional studies will be needed to confirm these results and to clarify other questions about dose and schedule of octreotide.

Management of diarrhea induced by tumors or cancer therapy.

Diarrhea is a common event in the clinical history of cancer patients. It can be caused by the presence of tumor or it can be a side effect of treatment. The latter problem is occurring more often because new drugs (CPT-11) or drug combinations (fluorouracil plus interferon or leucovorin) have diarrhea as the dose-limiting toxicity. The clinical use of octreotide, a long-acting somatostatin analogue, seemed to demonstrate an improvement in most diarrheal states induced by tumors (endocrine tumors) or by treatments (short bowel syndrome; chemotherapy-induced diarrhea).

Escalating dose of tegafur combined with oral etoposide in metastatic gastric carcinoma.

Fifteen patients with advanced gastric cancer received orally etoposide 100 mg daily for 14 days and escalating doses of tegafur. The starting dose was 400 mg daily. The maximum tolerated dose of tegafur was identified at 850 mg daily. Unacceptable toxicity was seen at 1000 mg, and consisted of diarrhea, stomatitis and leukopenia. Two partial responses were seen at 800 mg daily. In conclusion, our data show that etoposide and tegafur can be safely administered in combination by the oral route.

Neuroprotective effect of reduced glutathione on cisplatin-based chemotherapy in advanced gastric cancer: a randomized double-blind placebo-controlled trial.

PURPOSE: We performed a randomized double-blind placebo-controlled trial to assess the efficacy of glutathione (GSH) in the prevention of cisplatin (CDDP)-induced neurotoxicity. PATIENTS AND METHODS: Fifty patients with advanced gastric cancer treated with a weekly CDDP-based regimen were included in this study. In patients randomized to receive GSH, GSH was given at a dose of 1.5 g/m2 in 100 mL of normal saline solution over a 15-minute period immediately before CDDP administration, and at a dose of 600 mg by intramuscular injection on days 2 to 5. Normal saline solution was administered to placebo-randomized patients. Clinical neurologic evaluation and electrophysiologic investigations have been performed at baseline and after 9 (CDDP dose, 360 mg/m2) and 15 (CDDP dose, 600 mg/m2) weeks of treatment. RESULTS: At the 9th week, no patients showed clinically evident neuropathy in the GSH arm, whereas 16 patients in the placebo arm did. After the 15th week, four of 24 assessable patients in the GSH arm suffered from neurotoxicity versus 16 of 18 in the placebo arm (P = .0001). In confirmation of this neuroprotective effect, the neurophisiologic investigations, based on the evaluation of the median, ulnar, and sural sensory nerve conduction, showed a statistically significant reduction of these values in the placebo arm but not in the GSH arm, above all considering potential amplitude. In this trial, GSH also reduced hemotransfusion requirements (32 v 62 hemotransfusions) and treatment delay (55 v 94 weeks). The response rate was 76% (20% complete response) in the GSH group and 52% (12% complete response) in the placebo arm, confirming preliminary reports about the lack of reduction in activity of cytotoxic drugs induced by GSH. CONCLUSION: This study provides evidence that GSH is a promising and effective new drug for the prevention of CDDP-induced neuropathy, and that it does not reduce the clinical activity of chemotherapeutic drugs.

A pilot clinical trial of surgical adjuvant treatment with high-dose 6S-leucovorin/5-fluorouracil and radiation therapy for high-risk rectal carcinoma.

AIMS AND BACKGROUND: The study was performed to evaluate the feasibility of combining leucovorin (LV) with 5-fluorouracil (5FU) and radiation therapy as adjuvant treatment for high-risk rectal carcinoma. METHODS: Twenty-five patients with histologically proven adenocarcinoma of the rectum, at high-risk of recurrence after potentially curative resection (T3 NO, T and N1-2; MO), received 5FU (370 mg/m2) and 6S-LV (100 mg/m2) on days 1-5, 4 and 8 weeks after surgery. On treatment day 64, radiotherapy on the pelvis (50 Gy) was initiated. Finally, three further courses of 5FU/LV were given at intervals of 4 weeks beginning 28 days after the completion of radiotherapy. RESULTS: The treatment was generally well tolerated. We observed only 2 cases of grade III toxicity (diarrhea) during the third cycle of chemotherapy. No severe complications were recorded following the use of radiotherapy. The mean overall 5FU dose intensity was 92%. After a median follow-up of 24 months, 4 patients had relapsed (liver, lung, and pelvis, 2 cases). CONCLUSIONS: The association of LV to 5FU and radiation therapy seems to be feasible, with acceptable toxicity. The advantage of this combination, in terms of recurrence rate and survival with respect to 5FU/radiotherapy alone, will have to be evaluated in randomized trials.

Etoposide, leucovorin, 5-fluorouracil and interferon alpha-2b in elderly gastric cancer patients: a pilot study.

A total of 23 advanced gastric cancer patients older than 65 years received 500 mg/m2 5-fluorouracil i.v. on days 2-4, 120 mg/m2 vepesid i.v. on days 2-4, 150 mg/m2 6S-leucovorin on days 2-4, and 5 MU/m2 interferon alpha-2b on days 1-5, with cycles being repeated every 3 weeks. Toxicity was severe at an interferon (IFN) dose of 5 MU/m2; only one patient tolerated this dose. In 18 patients an IFN dose of 3 MU/m2 and in 3 other patients a dose of 4 MU/m2 could be given without producing toxicity. At an IFN dose of 5 MU/m2 the most common toxicities encountered were stomatitis (grade 4 in 1 patient and grade 3 in 12 patients), leukopenia (grade 4 in 1 patient and grade 3 in 5 patients), and thrombocytopenia (grade 3 in 3 patients). Two patients achieved a complete response and eight showed a partial response, resulting in an overall response rate of 45% [95% confidence interval (CI), 25%-64%]. The median survival was 7 months for all patients and 9 months for responding patients. In conclusion, without substantially increasing the toxicity, IFN can be added to the etoposide/leucovorin/5-fluorouracil combination, at a dose of 3 MU/m2. To verify the possible enhancement by IFN of the activity of this combination, a randomized trial is under way.

Oral cooling (cryotherapy), an effective treatment for the prevention of 5-fluorouracil-induced stomatitis.

Recently, a randomised study demonstrated the utility of oral cooling (cryotherapy) in the prevention of 5-fluorouracil (5FU)-induced stomatitis. In order to verify these results a confirmatory study, using identical treatment regimen, was initiated. 84 patients treated with a 5-FU-containing regimen were randomised to a control arm or to receive oral cryotherapy. End point evaluation was obtained by a global assessment of the physician's judgement and patients' description of mucositis severity graded 0-4. Mucositis was significantly reduced by cryotherapy considering both the first cycle of therapy (the mean toxicity score for cryotherapy was 0.59 and it was 1.1 for the control group, P < or = 0.05) and all the chemotherapeutic courses (the mean toxicity score for cryotherapy was 0.36 when it was 0.69 for the control group, P < or = 0.05). In conclusion, the present study confirms that cryotherapy can decrease 5FU-induced stomatitis and should be recommended for patients receiving bolus 5FU-containing regimens.

Cisplatin, 5-fluorouracil and interferon alpha 2b for recurrent or metastatic head and neck cancer.

On the basis of preclinical data suggesting the possibility of maximising the efficacy of 5-fluorouracil and cisplatin by interferon, a pilot clinical trial was initiated in recurrent and/or metastatic head and neck cancer. Thirty-four patients were treated with cisplatin at 100 mg m-2, followed by 5-fluorouracil at 1,000 mg m-2 by continuous infusion for 5 days. Interferon alpha 2b was administered at the dose of 3 million U i.m. daily for 7 days, beginning the day before chemotherapy. Courses were repeated every 3 weeks. Two patients achieved a complete remission, six a partial response, 14 had stable disease and 12 progressed on therapy, for an overall response rate of 23% (95% confidence interval 10-36%). Median survival time was 5 months. Toxicity was severe. Stomatitis, diarrhoea and myelosuppression were the most common side-effects. Because of the poor response rate and the presence of severe toxicity, in our opinion further clinical trials in head and neck cancer should be attempted only after a better definition in preclinical studies of interactions among 5-fluorouracil, cisplatin and interferon.

Recombinant human erythropoietin treatment in cisplatin-associated anemia: a randomized, double-blind trial with placebo.

PURPOSE: To evaluate the effect of exogenous recombinant human erythropoietin (rHuEPO) on the increase of hemoglobin levels and on the transfusion requirements in patients with cisplatin (CDDP)-induced anemia, we performed a double-blind randomized trial with placebo. PATIENTS AND METHODS: One hundred patients with CDDP-associated anemia (hemoglobin level < 90 g/L) were randomized to receive either placebo (saline solution) or rHuEPO (100 U/kg body weight subcutaneously) three times per week. The end points of this study were the increase in hemoglobin levels to greater than 100 g/L after 3, 6, and 9 weeks and the effect on transfusion requirements. RESULTS: Ninety-nine of 100 patients were assessable for response and toxicity. In the rHuEPO arm, mean hemoglobin levels were statistically significantly increased after the third, sixth, and ninth weeks of therapy (101.1 +/- 9.0, 102.4 +/- 6.6, and 105.1 +/- 9.4 g/L, respectively) compared with the mean baseline value (86.3 +/- 6.2 g/L). In the placebo arm, there were no increases in mean hemoglobin levels at the third, sixth, and ninth weeks (81.0 +/- 5.2, 81.3 +/- 9.2, and 81.2 +/- 11 g/L, respectively) compared with the mean baseline value (87.3 +/- 5.2 g/L). Furthermore only 20% of patients required blood transfusions in the rHuEPO arm versus 56% of patients in the placebo arm (P = .01), with a mean units of blood transfused per patient of 0.30 in the rHuEPO arm and 1.8 in the placebo arm (P = .01). Treatment was well tolerated, with no significant side effects. CONCLUSION: CDDP-induced anemia is corrected by rHuEPO, which results in reduced blood transfusion requirements.

Cytokinetic effects of interferon in colorectal cancer tumors: implications in the design of the interferon/5-fluorouracil combinations.

Interferon (IFN) has been shown to enhance the cytotoxic effects of 5-fluorouracil (5FUra) in colorectal cancer, and clinical trials with this combination resulted in higher response rate with respect to 5FUra alone. IFN is generally administered s.c. three times a week. This prolonged exposure could determine a block of tumor cells in the G0-G1 phase of the cell cycle, thus rendering tumor cells insensitive to 5FUra, an S-phase specific agent. In order to verify the presence of this block, 21 operable colorectal cancer patients were treated with IFN-alpha 2b at the dose of 3 megaunits every other day in the week before operation, while another 22 represented the control group. Samples of tumor tissue were taken at endoscopy and operation. [3H]Thymidine labeling index and flow cytometry were used to assess the S-phase fraction. In IFN treated patients, we found a significant statistical difference between the mean percentage of S-phase fractions evaluated either by labeling index (P = 0.00001) or by flow cytometry (P < 0.001). On the contrary, this difference was not present in the control group: labeling index, P = 0.06; flow cytometry, P = 0.08. Furthermore a significant increase in the G0-G1 phase of the cell cycle was found after IFN administration (P < 0.001) but not in the control group. Our results suggest that IFN reduces the S-phase fraction in colorectal cancer tumors. This action should be considered in the design of the 5FUra/IFN combination because it could decrease 5FUra activity, leading to a loss or a decrease in the advantage of 5FUra modulation by IFN.

A pilot clinical trial of postoperative adjuvant intraperitoneal cisplatin, 5-fluorouracil, 6S-leucovorin and interferon alpha 2b in patients with resected gastric cancer.

AIMS AND BACKGROUND: The study was performed to assess the toxicity and impact on relapse pattern of postoperative intraperitoneal cisplatin, 5-fluorouracil, leucovorin and interferon therapy as adjuvant treatment for gastric cancer patients who are at high risk for recurrence after potentially curative resection (T2 N1-2; T3-4 N any Mo). PATIENTS AND METHODS: Starting 14 to 21 days after potentially curative resection of primary gastric cancers, 22 patients were given intraperitoneal cisplatin, 60 mg/m2; 5-fluorouracil, 1000 mg/m2; 6S-leucovorin, 250 mg/m2; interferon alpha 2b, 10 MU/m2; every other week for six times. RESULTS: After a median follow-up of 24 months, 63% of patients were alive and free of disease. Eight patients had recurred; five had an intraabdominal component, and 3 had extraabdominal failure. Toxicity was mild: no grade III-IV WHO toxicity was observed. CONCLUSIONS: Intraperitoneal cisplatin, 5-fluorouracil, 6S-leucovorin and interferon is a tolerable therapy in the postoperative setting for patients with resected gastric cancer. These data make this approach interesting for the development of new programs of adjuvant therapy of high-risk gastric cancer.

Breast cancer developing after therapy for Hodgkin's disease.

Two patients developed breast cancer 14 and 8 years after treatment of Hodgkin's disease. Both had received mediastinal irradiation and MOPP chemotherapy. Because of the increased risk of breast cancer in women treated for Hodgkin's disease, as reported in the literature, we suggest the early initiation of periodic screening for breast cancer, to detect possible neoplasms at a more treatable stage.

Cisplatin-associated anaemia treated with subcutaneous erythropoietin. A pilot study.

In 20 patients with cisplatin-associated anaemia (haemoglobin less than 90 gl-1), recombinant human erythropoietin was administered subcutaneously three times a week on an outpatient basis. The initial dose was 50 Units Kg-1 of body weight. If response was not achieved within 3 weeks, dose was increased to 75 Units Kg-1. Using the same criteria further escalation to 100 Units Kg-1 was performed. If there was no response erythropoietin was terminated. Fifteen patients obtained an increase in haemoglobin to above 100 gl-1 which was considered as a clinical response in this study, with a dose of 50 Units Kg-1; one patient needed an erythropoietin dose of 75 Units Kg-1 and one a dose of 100 Units Kg-1. Only three patients required haemotransfusions and were considered non responders. Haemoglobin increases occurred despite continuation of cisplatin chemotherapy. In conclusion subcutaneous low dose of erythropoietin seems to be effective and safe in the treatment of cisplatin-induced anaemia.
