Stage III colon cancers: why adjuvant chemotherapy is not offered to elderly patients.

HYPOTHESIS: Adjuvant chemotherapy is not offered to elderly patients with stage III colon cancer. DESIGN: A retrospective review of hospital and office records. SETTING: A suburban community hospital. PATIENTS: The medical records of 69 patients with stage III colon cancer were reviewed. All identified from the Tumor Registry at Jersey Shore Medical Center, Neptune, NJ, were included in this study. RESULTS: Thirty-five patients (51%) did not receive adjuvant chemotherapy. After adjusting for age, women were 5.8 times less likely to receive chemotherapy (P = .002). Patients not receiving chemotherapy were significantly older (78.7 vs 70.4 years; P = .003) than those who received adjuvant chemotherapy. There was no relation found between the year of diagnosis and the administration of chemotherapy. There were 4 major reasons for not receiving chemotherapy: (1) not offered (n = 12, 34%), (2) refused (n = 11, 31%), (3) too old (n = 7, 20%), and (4) significant concomitant disease (n = 5, 14%). CONCLUSIONS: A large group of elderly patients who had been surgically treated for colon cancer and who were eligible for adjuvant chemotherapy either were not referred for treatment or refused treatment. This suggests a bias on the part of surgeons, primary care physicians, and patients against the use of chemotherapy in elderly patients.

Protection from the sun: a survey of area beachgoers.

There is a link between skin cancer and sunlight. A study of area beachgoers reveals gaps in public awareness about the hazards of ultraviolet light. Beachgoers, including children, are ideal target groups for educational programs on ultraviolet protection.

COP-BLAM multidrug infusion chemotherapies for lymphoma: results in a community hospital setting.

Twenty-two patients with malignant lymphoma were treated with three different COP-BLAM infusional chemotherapy protocols at the Jersey Shore Medical Center. The treatment group included 18 patients with large-cell lymphoma, 3 patients with Hodgkin's disease, and 1 patient with composite lymphoma (large-cell lymphoma and Hodgkin's disease). Three patients were treated with COP-BLAM III, 9 with COP-BLAM IV, and 10 with COP-BLAM V. The age of the patients at diagnosis ranged from 18 to 74 years, with a median age of 64 years. One patient had stage I bulky disease, 4 had stage II bulky disease, 3 had stage III disease, and 14 had stage IV disease. Twenty patients were evaluable for response; 2 were too early to evaluate. Complete response (CR) was seen in 18 of the 20 evaluable patients (90%). Potential cure (excludes non-lymphoma-related deaths) at 24 months is projected at 78%. Eleven patients are presently without disease and off therapy (55%). Projected failure-free survival at 2 years is 71% (a failure being death from any cause). Eleven of 22 patients developed 15 febrile episodes. Vincristine neuropathy was seen in 6 patients. Subclinical pulmonary fibrosis was seen in 1 patient. There was one cardiotoxic death. The COP-BLAM infusional protocols are highly effective, tolerable regiments that are applicable in community hospitals and can yield good response rates, with a high percentage of disease-free survivors in all age groups. The treatment can be completed in a short period with acceptable toxicity.

COPBLAM III: infusional combination chemotherapy for diffuse large-cell lymphoma.

COPBLAM III, a polychemotherapy regimen consisting of cyclophosphamide, infusional vincristine, prednisone, infusional bleomycin, doxorubicin, and procarbazine, was administered to 51 patients with diffuse large-cell lymphoma. Ninety-six percent of patients age 60 or younger achieved a complete response (CR); none have relapsed. Overall, 88% of patients are alive and well and potentially in the survival plateau. For patients greater than 60 years, CR was obtained in 73%, with 42% potentially in the survival plateau, the difference resulting in part from four relapses, three toxic deaths, and one presumed unrelated death. These results in the elderly were paralleled by a relatively reduced ability to tolerate therapy. Toxicity was primarily pulmonary, occurring in 39% of patients, two of whom died. With an overall CR rate of 84%, of which 92% are sustained at a median follow-up of 40 months, COPBLAM III represents a highly effective treatment in a sizeable cohort of patients.

Advances in chemotherapy for large cell lymphoma.

Three generations of chemotherapy regimens for the treatment of aggressive lymphomas have evolved in the past decade. The first-generation combination regimen, CVP, also known as COP (cyclophosphamide, vincristine, prednisone), produced maximum long-term survivals in considerably less than 20% of patients. With the MOPP (mechlorethamine, vincristine, procarbazine, prednisone) regimen, 40% of patients achieved complete remission (CR). This signal study was paralleled by other first-generation studies including CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone), HOP (doxorubicin, vincristine, prednisone), CHOP-Bleo/BACOP (CHOP plus bleomycin), and COMLA (cyclophosphamide, vincristine, methotrexate, leucovorin, cytarabine). None of the regimens was shown to be particularly superior to the others. Survival plateaus were seen in approximately 20% to 40% of patients. Second-generation therapies, COP-BLAM (cyclophosphamide, vincristine, prednisone, bleomycin, doxorubicin, procarbazine), ProMACE-MOPP (prednisone, methotrexate, doxorubicin, cyclophosphamide, etoposide, mechlorethamine, vincristine, procarbazine, prednisone), M-BACOD (methotrexate, bleomycin, doxorubicin, cyclophosphamide, vincristine, dexamethasone), and m-BACOD (same as M-BACOD, but with a moderate dose of methotrexate and modified leucovorin given on days 8 and 15 instead of just day 10) were characterized by an increasing number of drugs, more frequent administration of myelosuppressive agents, and flexible dose schedules. This new treatment intensity resulted in CRs in excess of 70%. The third generation regimens have been characterized by innovative concepts of chemotherapy, including alternative modes of drug administration, greater use of marrow-sparing, cycle-active, and/or putatively non-cross-resistant agents, and more frequent and/or intense dose administration. These regimens, COP-BLAM III, MACOP-B (methotrexate, doxorubicin, cyclophosphamide, vincristine, prednisone, bleomycin), ProMACE-CytaBOM (ProMACE plus cytarabine, bleomycin, vincristine, methotrexate), and high-dose doxorubicin with cytarabine, have produced over 80% CRs and survival plateaus in excess of 60%. In the COP-BLAM III regimen, 84% of patients achieved a pathologic CR. Overall, 65% of patients are alive, well, and free of disease, and potentially in the survival plateau. COD-BLAM IV (same as COP-BLAM, except dexamethasone is substituted for prednisone) is a new program that further intensifies treatment by using sequential, rather than alternate-cycle, infusions of bleomycin and vincristine. Results are still preliminary, with a short median follow-up of 19 months.(ABSTRACT TRUNCATED AT 400 WORDS)
