Screening for cancer of uterine cervix and approaches adopted in India.

Cervical cancer is the leading malignancy among Indian women. It has been estimated that in the absence of any control programme, the incident number of cervical cancer cases in the country would rise to 140 thousand by the turn of this century. Cytology screening remains the main stay for the control of cervix cancer. In the present communication the evidence available for screening for cancer of cervix has been presented. Difficulties in organising cervical cancer screening programmes in India and the alternative approach have been discussed.

Oral cancer among patients under the age of 35 years.

BACKGROUND: Cancer of the oral cavity is one of the commonest cancers among males. AIMS: To assess the aetiological factors, patient characteristics, treatment and the outcome in young patients with oral cancer. SETTINGS AND DESIGN: A retrospective descriptive study of patients under the age of 35 years with cancer of the oral cavity treated between 1982-1996, with the last follow-up till 2001, using the tumour registry data of Regional Cancer Centre (RCC), Trivandrum, Kerala, India. SUBJECT AND METHOD: The detailed clinical, treatment and follow-up data were obtained from the computerised records of RCC and recorded on a preset proforma. This was analysed with emphasis on age, sex, risk factors, site, histology, clinical extent and treatment methods and survival in the study group. STATISTICAL ANALYSIS: The survival analysis was carried by Kaplan-Meier method and the difference in survival was analysed using log-rank test. RESULTS: Out of 264 patients analysed, tongue was the commonest site identified in 136 (52%) patients followed by buccal mucosa in 69 (26%) patients. A male female ratio of 2.3:1 was observed with a significantly higher male preponderance in buccal mucosa (4.3:1). Prior exposure to tobacco or alcohol was noted in 59.4% patients, with more habitués in buccal mucosa cancer. Histological confirmation was present only in 83.7% patients and among them most were squamous cell carcinoma (85.9%). Radiotherapy, surgery or combined modalities of treatment were employed for majority of patients. The 5-year survival was 57.3%. T stage of the tumour was found to be significant in predicting disease free survival (P=0.03). CONCLUSIONS: The importance of early detection for clinical down staging is stressed. There is a need to investigate the aetiology of intra oral cancers in younger patients since a significant proportion (almost 40%) of these patients do not have associated risk factors for cancer.

Attributing death to cancer: cause-specific survival estimation.

Cancer survival estimation is an important part of assessing the overall strength of cancer care in a region. Generally, the death of a patient is taken as the end point in estimation of overall survival. When calculating the overall survival, the cause of death is not taken into account. With increasing demand for better survival of cancer patients it is important for clinicians and researchers to know about survival statistics due to disease of interest, i.e. net survival. It is also important to choose the best method for estimating net survival. Increase in the use of computer programmes has made it possible to carry out statistical analysis without guidance from a bio-statistician. This is of prime importance in third- world countries as there are a few trained bio-statisticians to guide clinicians and researchers. The present communication describes current methods used to estimate net survival such as cause-specific survival and relative survival. The limitation of estimation of cause-specific survival particularly in India and the usefulness of relative survival are discussed. The various sources for estimating cancer survival are also discussed. As survival-estimates are to be projected on to the population at large, it becomes important to measure the variation of the estimates, and thus confidence intervals are used. Rothman's confidence interval gives the most satisfactory result for survival estimate.

Acute abdomen in patients receiving chemotherapy.

OBJECTIVE: To assess the incidence of acute abdomen in patients receiving chemotherapy and to evaluate the factors affecting the clinical decision-making. MATERIAL AND METHODS: Retrospective analysis of surgical oncology references for the patients developing acute abdomen while receiving chemotherapy was carried out. A surgical oncologist reviewed each referral and a full work-up was carried out. Surgical interventions were carried out as and when deemed necessary. Response to treatment, whether surgical or conservative, was used as main outcome variable. RESULTS: Mean age of the patients was 37 years (7-58 years). Half of the patients were receiving chemotherapy for lymphoproliferative disorders, 13 for haematological malignancies and 3 for ovarian cancer. Clinical diagnosis was of acute appendicitis in 13, paralytic ileus in 9, typhilitis in 3 and intestinal perforation in 2, acute intestinal obstruction in 3, and obstructed hernia and intussception in one each. Six patients underwent surgery. Two patients expired postoperatively of progressive septicaemia and multi-system organ failure. CONCLUSION: Evaluation of cancer patients on chemotherapy is difficult. Tenderness, presence of peritoneal signs and absence of exaggerated bowel sounds are most important clinical signs, however they may be blunted by progressive neutropenia or corticosteroid administration. Decision to operate, should be made with extreme caution as mortality and morbidity after surgery is high.
