A combination of mitoxantrone, etoposide and prednisone in elderly patients with non-Hodgkin's lymphoma.

From January 1988 to December 1991, 55 elderly patients (14 pretreated and 41 previously untreated) with non-Hodgkin's lymphoma (NHL) entered a prospective study to evaluate the feasibility of a combination of mitoxantrone (7-9 mg/m2), VP 16-213 (150 mg, 2-hour infusion on day 1, and 200 mg per os on days 3 and 5) and low-dose prednisone (25 mg days 1-5) (MVP regimen), recycling every 21-28 days. The median age was 75 (range 64-93). All but 4 pretreated patients had intermediate- or high-grade lymphomas. Complete remissions were obtained in 22 of 40 (55%) evaluable previously untreated patients, and partial remissions in 10 (2 of these obtained complete remissions after radiotherapy), for an overall response rate of 80%. The median duration of response was 12 months. At 24 months the overall survival was 52% and the relapse-free survival was 31%. Of 14 pretreated patients complete remissions were obtained in 4 (29%) and partial remissions in 3. Granulocytopenia and fever were the most important side effects; two patients contracted bronchopneumonia and one of them died. Other toxicities were mild. We conclude that this combination chemotherapy is effective as first-line and salvage treatment in elderly patients with intermediate- and high-grade NHL, and that it is feasible on an outpatient basis, with manageable toxicity.

Experience with intraperitoneal alpha-2a interferon.

Eighteen patients affected with epithelial ovarian cancer have been treated by intraperitoneal alpha 2a-Interferon. The usual single dosage was 54 x 10(6) U at weekly intervals for four times (eight times in responders): 10 histologically confirmed complete remissions and 3 partial remissions have been obtained; the toxicity was represented by fever in the majority of the cases, by abdominal discomfort in some cases, and by a mild transitory neurological complication in 1 case. Seventeen of 18 patients were pretreated, and 11 of 18 had only cytologic and/or microscopic disease. alpha 2a-Interferon has proven to be very effective and moderately toxic in microscopic peritoneal disease of ovarian epithelial cancer previously treated with extensive surgery and intravenous cytotoxic chemotherapy.

Carboplatin plus 5-fluorouracil and leucovorin in previously treated patients with metastatic breast cancer.

The commonly reported second-line chemotherapy regimens administered for metastatic breast cancer usually induce few responses, which last no more than 4 to 8 months. We used carboplatin 50 mg/m2 on days 2, 3, and 4 of each course, leucovorin 500 mg/m2 on days 1 through 5 in 30-minute infusions, and 5-fluorouracil (5-FU) 375 mg/m2 intravenous bolus 1 hour after each leucovorin dose to treat 32 patients with metastatic breast cancer. Six patients had previously received treatment with only one cytotoxic chemotherapy regimen, usually CMF (cyclophosphamide/methotrexate/5-FU). Twenty-six patients had received treatment with two or more regimens of chemotherapy previously, and most of them also had received radiotherapy and endocrine manipulations. Fifteen patients had visceral deposits. In cases of excessive or persistent toxicity, single daily doses were not reduced, but the start of the next course was delayed or its duration reduced. Of 26 heavily pretreated patients, 12 responded, primarily those with disease in lymph nodes, skin, breast, and pleura. One patient with liver deposits had a complete remission confirmed at laparoscopy and echogram. Survival was probably prolonged, with a median duration of response of 5 months (range, 3 to 22+), and moderate side effects that did not compromise quality of life during treatment. The probability of response was not related to the type of pretreatment (with or without 5-FU) nor to response to previous treatments.

Chemotherapy for invasive thymoma. A 13-year experience.

From 1977 to 1990, 37 patients with Stage III or IV invasive thymoma (20 men and 17 women; median age, 40 years of age) were referred for chemotherapy to the Padova Medical Oncology Department. All patients initially received the same regimen (50 mg/m2 of cisplatin and 40 mg/m2 of doxorubicin intravenously (IV) on day 1, 0.6 mg/m2 of vincristine IV on day 3, and 700 mg/m2 of cyclophosphamide IV on day 4 [ADOC]), recycling at monthly intervals. No life-threatening side effects were noted. The overall clinical response rate (complete response plus partial response) was 91.8%, with 43% complete remissions. Median duration of response and survival were 12 months (range, 2 to 96+ months) and 15 months (range, 5 to 96+ months), respectively. Seven of the 16 complete remissions were pathologically confirmed at subsequent thoracotomy. Other chemotherapy combinations and radiation therapy have been applied as second-line treatment, achieving only minimal responses. In the opinion of the authors, such chemotherapy deserves evaluation for adjuvant and neo-adjuvant treatment of invasive (and/or inoperable) thymoma due to the high complete response rate and overall response rate.

Combined chemotherapy with bleomycin, adriamycin, and platinum in advanced thyroid cancer.

Twenty-two advanced consecutive thyroid cancer patients with varying histologies were treated with the so called BAP regime which consisted of bleomycin (B) 30 mg a day for three days, adriamycin (A) 60 mg/m2 iv in day 5, and cisplatinum (P) 60 to mg/m2 iv in day 5. Patients with progressive, symptomatic recurrent or disseminated disease unresponsive to hormonal and/or isotopic treatment were eligible. Nine patients had an objective response: two long-lasting complete and seven partial responses were observed out of 21 evaluable patients. Stable disease was observed in four additional patients. The median duration of response was 12 months (range, 6-29). The total series experienced a median survival of 11 months (range, 1 to 57), with 2 patients actually disease free. Several histologic types of thyroid carcinoma responded, but the best responses were observed in medullary and anaplastic giant-cell carcinomas. Toxicity was reversible in all but one patient. Of the patients failing on BAP chemotherapy three responded to a four drug second line combination containing vincristine, fluorouracil, BCNU and methotrexate. BAP regime can achieve reasonable palliation, and probably increases survival, in poor-prognosis thyroid cancers.

Lymphomas in the elderly.

The elderly patients with lymphoma suffer from a relevant excess mortality, both during treatment and in the course of follow-up: various causes contribute, including: 1) "generational" mortality; 2) iatrogenic mortality due to unexpected organ/system fragility; 3) low remission rates, due to low tolerated doses and, 4) a high prevalence of second tumors. The difficulty in achieving high cure rates begins after age 50 and steadily increases for patients over 60, 70 and 80. Less aggressive staging procedures are justified, and the modern visualizing techniques provide alternatives to lymphangiography and laparosplenectomy. In HD, local radiation instead of Total Nodal Irradiation, and doses of 30 or even 20 Gy may be administered for stages I and II; for stages III and IV the ChlVPP and the NOVP or the "ABVD without D" regimens may be adopted. After chronological and/or biological age 80, sequentially administered single agents produce an effective palliation, allowing for a good quality of life during treatment, and often obtain a reasonable prolongation of survival. Many NHL of elderly patients are indolent in their course, and a "watch and wait" policy is often in the true interest of the patient; when local aggressiveness only is apparent, a local low dose radiation may be considered. For advanced stage, treatment-requiring low-grade-NHL, oral chlorambucil plus or minus low dose steroids (or prednimustine) should be considered in alternative to watch and wait. For high grade, aggressive NHL, chemotherapy with short, non-Methotrexate-containing programs like POCE, NOSTE, P-VABEC, or other variations of MACOP-B are acceptable. Beyond age 80, or when other factors deteriorate the chances for survival, single agents like VM 26, or simple combinations of VP 16 + Prednimustine or VP 16 and Mitoxantrone may be adopted.

Alpha-2 interferon and 5-fluorouracil in advanced colorectal cancer.

A total of 21 untreated patients (5 males, 16 females; median age, 55 years; range, 28-72) with advanced measurable colorectal carcinoma were treated with an association of 5-fluorouracil (1000 mg/weekly) and alpha-2 interferon (three times a week s.c.: 6 x 10(6) U in the 1st month, 9 x 10(6) U in the 2nd month, 12 x 10(6) U in the 3rd month and then 18 x 10(6) U) until maximum response or progression of disease. Sites of disease involved liver in 10 patients, lung in 6, supraclavicular lymph nodes in 3, skin in 1, abdomen in 4, and vagina in 1 patient. Nine responses (42.8%) were documented (4 complete and 5 partial) with metastases confined to the liver, lung, nodes and skin. Median duration of response was 11 months (range, 4-17+) and median survival was 10 months (range, 2-17+). Side effects (fever, flu-like syndrome and leukopenia) required a dose reduction of 5-fluorouracil in 8 patients and interferon in 2 patients.

Leukemia following Hodgkin's disease.

To investigate the effect of different treatments for Hodgkin's disease on the risk of leukemia, we used an international collaborative group of cancer registries and hospitals to perform a case-control study of 163 cases of leukemia following treatment for Hodgkin's disease. For each case patient with leukemia, three matched controls were chosen who had been treated for Hodgkin's disease but in whom leukemia did not develop. The use of chemotherapy alone to treat Hodgkin's disease was associated with a relative risk of leukemia of 9.0 (95 percent confidence interval, 4.1 to 20) as compared with the use of radiotherapy alone. Patients treated with both had a relative risk of 7.7 (95 percent confidence interval, 3.9 to 15). After treatment with more than six cycles of combinations including procarbazine and mechlorethamine, the risk of leukemia was 14-fold higher than after radiotherapy alone. The use of radiotherapy in combination with chemotherapy did not increase the risk of leukemia above that produced by the use of chemotherapy alone, but there was a dose-related increase in the risk of leukemia in patients who received radiotherapy alone. The peak in the risk of leukemia came about five years after chemotherapy began, and a large excess persisted for at least eight years after it ended. After adjusting for drug regimen, we found that patients who had undergone splenectomy had at least double the risk of leukemia of patients who had not, and an advanced stage of Hodgkin's disease carried a somewhat higher risk of leukemia than Stage I disease. We conclude that chemotherapy for Hodgkin's disease greatly increases the risk of leukemia and that this increased risk appears to be dose-related and unaffected by concomitant radiotherapy. In addition, the risk is greater for patients with more advanced stages of Hodgkin's disease and for those who undergo splenectomy.

Evaluation of chromosomal aberrations in lymphocytes and micronuclei in lymphocytes, oral mucosa and hair root cells of patients under antiblastic therapy.

In 7 patients undergoing antiblastic chemotherapy for the first time, the structural chromosomal aberration (CA) test in peripheral lymphocytes was compared with the micronucleus (Mn) test in lymphocytes, in oral cavity cells and in hair root cells of the scalp. The last test is being proposed for the first time. The CA and Mn frequencies induced by chemotherapy were compared with the baseline (pretreatment) frequencies of the patients and with confidence limits calculated in 4 control groups studied for CA, Mn in lymphocytes, Mn in oral cavity cells and Mn in hair root cells, respectively. The studied chemotherapies induced a clear cytogenetic effect in at least 2 of the tests studied with the exception of interferon-alpha 2b (patient 6) and interferon + low doses of cis-platinum (patient 2) which did not appear to cause evident chromosomal damage. The response to chemotherapy is generally characterized by an increase in Ca and Mn, reaching a peak value and then decreasing in the following weeks. The CA test proves to be the most sensitive despite the fact that CA were analyzed in an average of 100 cells per sample against the 500-3000 cells analyzed for Mn. The efficiency of Mn to detect CA is in the following order: Mn in lymphocytes greater than Mn in buccal cells greater than Mn in hair root cells. The last test appears to be very promising but, used following the current method, does not appear suitable to monitor acute exposure.

Modulating fluorouracil with different drugs: the Padua experience.

Several clinical experiences from Padua, Italy confirm that 5-fluorouracil may be usefully modulated by the addition of leucovorin, and especially by platinum and alpha interferon. The intra-arterial and intraperitoneal administration of such synergistic combinations has also proved to be of benefit in special subsets of patients. Perspectives of further studies are examined.

Response and toxicity of cisplatin and 120-h 5-fluorouracil infusion in pretreated and untreated patients with advanced epidermoid cancer of the head and neck.

Eighty-two patients with advanced or recurrent squamous cell carcinoma of the head and neck were treated with bolus cisplatin and 120-h infusion of 5-fluorouracil. Among 49 pretreated patients, there were 9 complete and 12 partial responses, for an overall response rate of 43% and a median estimated survival of 8 months. Hematologic toxicity in this group was relevant, with 4 early deaths and 30% of cases with moderate to severe leukopenia; mucosal and renal toxicities were also important. Among 33 patients with no prior therapy, there were 8 complete and 17 partial responses, for an overall response rate of 76%. Fifteen of the 25 responding patients received subsequent locoregional treatment. The median estimated survival in this group was 29 months. Hematologic, mucosal, and renal toxicities were only mild to moderate. Episodes of possible 5-fluorouracil-related cardiotoxicity were recorded in both pretreated and untreated patients. Twelve of 41 partial responses observed after the second cycle of therapy were converted to complete responses with a third (8 cases) and also a fourth (4 cases) course. This study confirmed that cisplatin plus 5-fluorouracil is a first-choice combination in previously untreated patients. Definitive evidence that chemotherapy can favorable influence survival awaits confirmation by randomized trials, using a control arm with conventional locoregional treatment. In previously treated patients with recurrent disease, less intensive regimens not requiring hospitalization seem more useful for the quality of life.

Intrapericardial instillation of platin in malignant pericardial effusion.

Six patients (four men and two women) affected by malignant pericardial effusion, as confirmed by cytologic examination, were treated with direct intrapericardial administration of cisplatin. Median age was 36.8 years (range, 18 to 56 years). After insertion of a radiopaque polyurethane catheter (Centracath Vygon, Laboratoires Pharmaceutiques, Vygon-Ecouen, France), fluid was drained and cisplatin (10 mg in 20 ml of normal saline) was instilled over 5 minutes on 5 consecutive days (total cisplatin dose, 50 mg). At the end of the course, the catheter was withdrawn. Courses were repeated every 2 or 3 weeks in case of fluid reaccumulation. The median number of courses was two, with a range of one to three courses. Three patients achieved complete response and all three died of primary disease progression without evidence of pericardial recurrence or stricture. Mild nausea occurred in all patients. No hematologic and renal toxicity and local or infectious complications were observed.

High-dose medroxyprogesterone in disseminated breast cancer. Correlation between bioavailability and clinical response.

Clinical response to high-dose medroxyprogesterone (MPA), administered following three different routes of administration (i.m., p.o. + i.m., p.o.) and monitoring drug plasma levels, was evaluated in pretreated advanced breast cancer patients. Fifty-eight of 68 eligible patients were considered evaluable for response. Age ranged between 36 years and 82 years. Fifty-six of 58 evaluable patients were postmenopausal. An overall remission rate of 48% was achieved with i.m. MPA, 50% with combined (i.m. + p.o.) modalities; only a 19% remission rate was recorded in the p.o. group. Response rate and MPA plasma concentrations were correlated, and a drug level of 80 ng/ml, by means of a GLC method, seems to identify a subset of patients with high probability of response. Only mild toxic effects were recorded.

A 5-day regimen of cyclophosphamide, adriamycin, platinum (CAP) in refractory breast cancer.

The activity of the association of cis-platinum with Adriamycin and cyclophosphamide (CAP), as "rescue" chemotherapy for the treatment of refractory and relapsing advanced breast cancer, is presented. Of 42 evaluable patients, previously treated with chemotherapy +/- hormone therapy, 4 (9.5%) achieved a complete response, 15 (35%) had a partial response (CR + PR = 45%). Major toxicity observed was: nausea and vomiting in 95% of patients and leukopenia in 60%.

Localized ovarian cancer: surgery plus chemotherapy.

Fifty-four patients were referred to Medical Oncology after operation for "limited" ovarian cancer; 7 were excluded because immediate restaging showed evidence of macroscopic spread to structures outside the true pelvis, and 10 will be considered separately because of microscopic spread shown only by cytology. Thirty-seven patients (31 stage I and 6 stage II) were accordingly accepted as "localized", because peritoneal cytology and diaphragm and omental plus parietal peritoneum histology could rule out the spread to the large abdominal cavity. Some of the referred patients had been operated in nearby hospitals; the Padua GYN Cin. performed 14 of the 37 first surgery operations and 30 of the 37 second look operations. All patients soon after surgery underwent first-line chemotherapy with 5 courses of high dose adriamycin plus cyclophosphamide for 4 months, then surgical second look, and second-line non-cross-resistant chemotherapy for 3 months. During the second look the organ and tissue removal was completed in those 21 patients having received "limited" first surgery. Two patients died within 5 years from admission, so that the overall 5 year actuarial survival from referral is 93% for the entire group with 11 patients still at risk; 87% are disease free 5 years after the second look with 7 at risk. Subdivision of the patients according to "adequate" vs. "limited" first surgery, may select a group (the "adequate" one, composed of 16 patients) completely free from relapses, up to now. The complex therapeutic program described seems to offer long term relapse-free survival to the majority of patients, while the few failures seem closely related with inadequacies of the initial surgical procedure.

Peptichemio in advanced breast cancer: a clinical evaluation in 32 patients.

A clinical evaluation of peptichemio (40-45 mg/m2/day for 3 days every 3-4 weeks) was conducted in 32 patients with advanced breast cancer, 28 of whom were evaluable for both toxicity and response. The overall response rate was 18% (one complete remission and four partial remissions), with a median duration of 4 months (range, 2-6). The major side effects were cumulative myelotoxicity, phlebitis, mild nausea, and vomiting. A posttreatment heparin infusion was used to prevent phlebitis.
