Practical consensus recommendations regarding role of postmastectomy radiation therapy.

The use of radiation therapy after mastectomy (PMRT) has been limited to those patients who are at significant risk of cancer recurring in the chest wall or in the nodal basins. The use of PMRT has been widely accepted for patients with four or more positive lymph nodes,[1],[2] but there is still controversy regarding the value of PMRT for those with one to three positive nodes. This expert group used data from published literature, practical experience and opinion of a large group of academic oncologists to arrive at these practical consensus recommendations for the benefit of community oncologists.

Isolated hypoglossal nerve palsy due to skull base metastasis from breast cancer.

We describe a 44-year-old woman who presented with an isolated unilateral hypoglossal nerve paralysis caused by a skull base metastasis from breast cancer. The patient had a modified radical mastectomy followed by local radiotherapy and adjuvant chemotherapy. Fourteen months later she presented with difficulty in speaking. Physical examination revealed an isolated left hypoglossal nerve paralysis. The MRI scan showed a mass lesion involving the left occipital condyle extending into hypoglossal canal.

A non-randomized comparison of two radiotherapy protocols in inoperable squamous cell carcinoma of the oesophagus.

We report an audit of two different telebrachytherapy schedules in inoperable carcinoma of the oesophagus. Between October 1990 and December 1996, 108 patients with a Karnofsky performance status > or = 50 were selected from our database on the basis of intention to treat by telebrachytherapy. Teletherapy in the low dose group L (55 patients) consisted of 35 Gy in 15 fractions over 3 weeks, while that in the high dose group H (53 patients) consisted of 50 Gy in 25 fractions over 5 weeks. The choice of teletherapy dose was based on physician preference. The high dose rate intraluminal radiotherapy that followed 2 weeks later was identical in both groups and consisted of two applications of 6 Gy, a week apart. The pretreatment disease characteristics of the patients in both arms were similar. Relief of dysphagia was obtained in 49% of the patients in group L and in 75% of those in group H (chi2: P = 0.004). The median dysphagia-free interval was 0 and 7 months in groups L and H respectively (log-rank: P = 0.06), while the median overall survival was identical at 8 months (log-rank: P = 0.21) for both groups. The probability of survival at 1, 2 and 5 years was 34.8% versus 35.8%, 14.5% versus 13.9% and 0% versus 10% for groups L and H respectively. Morbidity in the form of ulcers, strictures and fistulae were observed in 9%, 7% and 5% of patients in group L compared with 8%, 8% and 13% in groups H respectively. This audit suggests that the protocol used in group H, when compared with group L, results in a greater proportion of patients being rendered dysphagia free, with a statistical trend towards a greater sustainment of dysphagia relief on follow-up.

Primary lymphoma of the lung: a report of two cases.

Two cases of primary lung lymphoma B and T-cell type are reported. Their management with chemoradiotherapy is presented along with brief review of literature.

Primary brain lymphoma. A brief review of clinical aspects and management.

Primary C.N.S. lymphoma is a rare tumor. Five such cases were treated in our clinic between January, 1991, and October, 1993. Four patients had tumor decompression and one had total resection. All of them received radiotherapy (radiation dose 40 Gy) and chemotherapy. One patient expired during the immediate postoperative period. Four patients showed a disappearance of the tumor on CT scan after the complete course of therapy of 9 months. Three patients showed recurrence intracranially at 15, 12, and 10 months. All patients died during follow up except one, who has been alive without recurrence for 10 months. Median survival was 13 months.

Radiation therapy alone and in combination with bleomycin and 5-fluorouracil in advanced carcinoma esophagus.

This presentation is a randomized prospective study of 74 patients of squamous cell carcinoma of esophagus divided into two groups. First group was treated with radical radiation alone and the other with radical radiation and combination of bleomycin and 5-FU. Analysis at the end of two years showed that the patients treated with addition of chemotherapy had an overall survival of 23 percent as compared to nine percent in the radiation alone group (P less than 0.05).

Splenic irradiation in chronic myeloid leukemia.

Results of splenic irradiation as the initial and only method of treatment are reported in 25 patients with chronic myeloid leukemia. Peripheral remission was induced in all the patients. Induction was achieved after a short period of 11 to 30 days in the majority of the patients, the longest period being 40 days. Several patients were in remission 9 months after treatment. The results are compared with those obtained by chemotherapy. Some advantages of splenic irradiation over chemotherapy are emphasized.
