Impact of age on the use of adjuvant treatments in patients undergoing surgery for colorectal cancer: patients with stage III colon or stage II/III rectal cancer.

BACKGROUND: Many older patients don't receive appropriate oncological treatment. Our aim was to analyse whether there are age differences in the use of adjuvant chemotherapy and preoperative radiotherapy in patients with colorectal cancer. METHODS: A prospective cohort study was conducted in 22 hospitals including 1157 patients with stage III colon or stage II/III rectal cancer who underwent surgery. Primary outcomes were the use of adjuvant chemotherapy for stage III colon cancer and preoperative radiotherapy for stage II/III rectal cancer. Generalised estimating equations were used to adjust for education, living arrangements, area deprivation, comorbidity and clinical tumour characteristics. RESULTS: In colon cancer 92% of patients aged under 65 years, 77% of those aged 65 to 80 years and 27% of those aged over 80 years received adjuvant chemotherapy (χ2trends < 0.001). In rectal cancer preoperative radiotherapy was used in 68% of patients aged under 65 years, 60% of those aged 65 to 80 years, and 42% of those aged over 80 years (χ2trends < 0.001). Adjusting by comorbidity level, tumour characteristics and socioeconomic level, the odds ratio of use of chemotherapy compared with those under age 65, was 0.3 (0.1-0.6) and 0.04 (0.02-0.09) for those aged 65 to 80 and those aged over 80, respectively; similarly, the odds ratio of use of preoperative radiotherapy was 0.9 (0.6-1.4) and 0.5 (0.3-0.8) compared with those under 65 years of age. CONCLUSIONS: The probability of older patients with colorectal cancer receiving adjuvant chemotherapy and preoperative radiotherapy is lower than that of younger patients; many of them are not receiving the treatments recommended by clinical practice guidelines. Differences in comorbidity, tumour characteristics, curative resection, and socioeconomic factors do not explain this lower probability of treatment. Research is needed to identify the role of physical and cognitive functional status, doctors' attitudes, and preferences of patients and their relatives, in the use of adjuvant therapies.

Medical oncology future plan of the Spanish Society of Medical Oncology: challenges and future needs of the Spanish oncologists.

PURPOSE: The SEOM Future Plan is aimed at identifying the main challenges, trends and needs of the medical oncology speciality over the next years, including potential oncologist workforce shortages, and proposing recommendations to overcome them. METHODS: The estimations of the required medical oncologists workforce are based on an updated Medical Oncologist Register in Spain, Medical Oncology Departments activity data, dedication times and projected cancer incidence. Challenges, needs and future recommendations were drawn from an opinion survey and an advisory board. RESULTS: A shortage of 211 FTE medical oncologist specialists has been established. To maintain an optimal ratio of 158 new cases/FTE, medical oncology workforce should reach 1881 FTE by 2035. CONCLUSIONS: Main recommendations to face the growing demand and complexity of oncology services include a yearly growth of 2.5% of medical oncologist's workforce until 2035, and development and application of more accurate quality indicators for cancer care and health outcomes measure.

Phase II clinical trial of cisplatin, 5-fluorouracil, and ifosfamide as treatment for advanced locoregional head and neck carcinoma.

The association of ifosfamide with cisplatin and 5-fluorouracil for the management of advanced squamous cell carcinoma of the head and neck was assessed in this trial. Ifosfamide was given initially to 12 patients in combination with standard fixed doses of cisplatin and 5-fluorouracil, at 1,000 mg/m2 daily on days 2, 3, and 4. Two patients died of neutropenia and severe infection, and the authors recruited seven more patients who were treated with a lower dose of ifosfamide, 800 mg/m2 daily on days 2, 3, and 4. One of the seven patients died of neutropenia and severe infection. Three complete remission were observed in 18 patients evaluable for efficacy. The study was closed early because of the severe toxicity profile demonstrated by this scheme and because of no clear advantage in efficacy versus cisplatin plus 5-fluorouracil combinations.

Sequential combination chemotherapy for malignant germ cell tumors of the ovary.

Fourteen patients with malignant ovarian germ cell tumors were treated postoperatively with a short-term, sequential regimen combining cisplatin, vincristine, methotrexate, bleomycin, dactinomycin, cyclophosphamide, etoposide, Adriamycin (Adria Laboratories, Columbus, OH), and vinblastine (POMB/ACE/PAV). Two patients had Stage I disease, Five had Stage II, five had Stage III, and two had Stage IV. The histologic diagnosis was immature teratoma in five cases (two cases were Grade 2 and three cases were Grade 3) endodermal sinus tumor in two cases, dysgerminoma in three cases, and mixed germ cell tumors in four cases. The chemotherapy regimen appeared to be highly effective against all histologic types, including advanced stages, with 12 of 14 (86%) overall sustained remissions. The median duration of treatment was 5 months. The toxicity of the regimen, which contained low total doses of cisplatin and bleomycin, was only moderate. After a median follow-up of 53+ months, 13 patients were alive without evidence of disease. The results and toxicity obtained were compared with those from other currently used regimens. Also, some comments on initial surgery and second-look surgery are given.

Follow-up of breast cancer stages I and II. An analysis of some common methods.

A retrospective analysis of the follow-up methodology was done in 343 cases of breast cancer Stages I and II, in order to ascertain the effectiveness of the explorations performed and the usefulness of the follow-up program. The actuarial probability of relapse at 6 years was 35% for the 237 patients with negative axillary nodes and 46% for the 106 patients with nodal involvement. Fifty-eight per cent of the relapses were detected by the patients themselves, 24% of relapses were found by physical examination and 9% of relapses were discovered in chest radiographs, leading to 91% of relapses diagnosed by combination of these explorations. The authors conclude that follow-up methodology for these patients could be limited to the above-mentioned methods, without significant reduction of curability or survival possibilities after relapse.

Locally advanced breast cancer with inflammatory component: a clinical entity with a poor prognosis.

Locally advanced and inflammatory carcinomas of the breast are two distinct entities, with widely accepted differential clinical criteria. We describe a particular type of locally advanced cancer which acquires during its evolution inflammatory characteristics, although limited to a small area of skin and thus not accomplishing the common diagnostic criteria of inflammatory carcinoma. When comparing this type of tumors, named locally advanced cancer with inflammatory component, to other locally advanced cancers, some remarkable differences are found: there is a preponderance of younger patients, premenopausal or perimenopausal, with a greater percentage of poorly differentiated tumors and negative estrogen receptors. Their evolution and survival are similar to that of inflammatory carcinomas; thus, we conclude they should be considered and treated as inflammatory carcinomas. Finally, the prognostic limitations of the TNM classification are discussed and some adjustments for future classifications are suggested.
