Association Of Weight Change In Breast Cancer Patients Undergoing Tamoxifen Treatment At A Tertiary Care Centre, Sindh, Pakistan.

BACKGROUND: Tamoxifen is a selective oestrogen receptor modulator; in the breast, it decreases the growth and proliferation of breast epithelial cells. We assessed the weight change after Tamoxifen use in breast cancer patients. METHODS: This was a single-centred, prospective, observational cohort study. All patients diagnosed with breast cancer with ER and/or PR positivity were enrolled in the study. Out of these, 90 patients who have been prescribed Tamoxifen treatment either in adjuvant or palliative setting gave their consent to participate. Demographic data, treatment plan, menstrual status, weight, BMI, serum fasting lipid profile, change in diet, and change in physical activity were recorded at the time of diagnosis and then quarterly until 1 year of treatment. RESULTS: A mean age of 42.12±8.5 years was reported, and the mean weight was 62.22±10.6 kg. The majority of the patients, i.e., 68 (75.55%) had advanced tumour stages (III and IV). The study reported that the mean weight of the patients changed significantly at different time intervals during the treatment course (p<0.0005). Moreover, there was an upward trend in weight from the time of starting Tamoxifen to 3-months (62.22±1.51 kg vs 62.88±1.45 kg, respectively). There was a statistically significant increase in weight at 6-month, 9-month, and 12-month of Tamoxifen treatment (63.72±1.46 kg, 64.35±1.42 kg, 65.12±1.44 kg, respectively). Also, most of the patients gained weight as time passed by. CONCLUSIONS: This study indicated that Tamoxifen has a significant correlation with the increase in weight in hormone receptor-positive breast cancer patients in our population.

Cytogenetic Abnormalities In Acute Myeloid Leukaemia Patients.

BACKGROUND: Acute myeloid leukaemia (AML) is malignant neoplasms of myeloid cells categorized by clonal expansion of hematopoietic blasts of myeloid lineage in peripheral blood and bone marrow. The aim of current study is to identify the common cytogenetic abnormalities in AML patients presenting at a tertiary care hospital of Pakistan. METHODS: It was a cross-sectional study conducted at the department of Medical oncology of the Jinnah Postgraduate Medical Center, Karachi from Jun 2017- Jan 2019. The non-probability consecutive sampling technique was used to select patients. Total 92 cases of AML of age 15-55 years of either gender were included in the study. The detection of cytogenetic abnormality was done on the bone marrow biopsy. The cytogenetic abnormalities were classified into the three cytogenetic risk groups as favourable, intermediate and unfavourable. For analysis of data SPSS 23 version was used. RESULTS: The cytogenetic abnormalities were detected in 34 (37%) of the AML patients while 58 (63%) patients had normal cytogenetic. Thirty-two females (34.8%) had a normal cytogenetic (46; XX), and 15 females (16.3%) had various cytogenetic abnormalities. Twenty-six males (28.3%) had normal cytogenetic (46; XY) and 19 males (20.7%) had various cytogenetic abnormalities. Most of the patients were in intermediate risk group (67.4%), followed by favourable (17.4%) and unfavourable risk group (15.2%). The most frequent chromosomal abnormalities observed were complex cytogenetic which was detected in 5 AML patients. CONCLUSIONS: In the present study cytogenetic abnormalities were found in 37% of AML patients. Sixty-seven of the AML patients were in intermediate risk group and five patients had complex cytogenetic. Hence the cytogenetic analysis provides significant information regarding prognosis of AML patients and the cytogenetic abnormalities are less than international literature.

Response Rate of Cisplatin Plus Docetaxel as Primary Treatment in Locally Advanced Head and Neck Carcinoma (Squamous Cell Types).

OBJECTIVE: To evaluate the response rate of Cisplatin plus Docetaxel in the treatment of locally advanced head and neck squamous cell carcinomas (HNSCC) at a tertiary care hospital in Karachi, Pakistan. MATERIALS AND METHODS: It was a longitudinal study, conducted at the Department of Medical Oncology, Jinnah Postgraduate Medical Center, Karachi, Pakistan from December 2018 to June 2019. One hundred patients of age 14-66 years of age of either gender with histologically proven Squamous Cell Carcinoma of Head and Neck, Stage III and IV (locally advanced) with no distant metastases were included in the study. Patients who were declared unresectable by the otolaryngologist and those with delayed appointment for radiation were given 3 cycles of Induction Chemotherapy with Cisplatin and Docetaxel, both at a dose of 75mg/m2 3 weekly. After 3 cycles, CT scan was repeated to assess the clinical response. Those patients who had partial or complete response as per RECIST criteria were re-assessed by the otolaryngologist and were planned for surgery if disease became resectable while other patients were referred for Concurrent Chemo-Radiation Therapy (CCRT). SPSS version 23 was used to analyze data. RESULTS: The partial response was achieved in majority of the patients after Induction Chemotherapy with Docetaxel and Cisplatin (62%) with a complete response in 12 %. However, 22% showed progression of the disease, and 4% showed stable disease. The most frequent side effects observed were diarrhea (62%) and neutropenia (57%). CONCLUSION: Induction chemotherapy with Cisplatin and Docetaxel is a promising regimen with good response and favorable toxicity profile and can be considered as a potentially effective outpatient regimen for locally advanced squamous cell carcinoma of head and neck.
