ABSTRACT
Soft tissue sarcomas form 1% of all cancers and are rare. The lower limb is one of the commonest sites of sarcoma, with the thigh accounting for the majority of these tumors. Large tumors abut the neurovascular bundles both anteriorly and in the hamstring compartment. Nerve involvement, especially the major nerves such as the femoral and the sciatic, by these tumors, was considered to be an absolute contraindication for limb salvage procedures. We present our data of major nerve resection without amputation, in an attempt to demonstrate the possibility of equivalent functional and oncological outcomes in these rare tumors. A total of 86 cases of extremity soft tissue sarcomas were operated on during the period September 2019 to September 2022, of which there were 12 cases of major nerve resections of the lower extremity. These patients were followed up and their clinicopathological data collected and analyzed. The functional outcome was recorded at different intervals. Of the 12 patients who underwent nerve resection along with the tumor, only 1 patient developed a local recurrence. Two patients developed multiple lung metastases, and the other 9 patients are alive and free of disease, with a median follow-up of 26 months. The MSTS score was assessed at 1 month post-surgery, 3 months, 6 months, and 1 year post-surgery. Except for one patient where the score was 20%, all the other patients had scores of 80% or more. Major nerve involvement by soft tissue sarcomas is not an indication for amputation. Limb salvage can be performed with no effect on the oncological outcomes.
ABSTRACT
To audit the use of breast conservation surgery for breast cancer treatment in a tertiary care centre over a 7-year period, and also to chart the clinical, demographic and pathological characteristics of breast cancer patients treated in the setting of a referral centre in a middle income (MDI) group country. A retrospective analysis of the case records of all patients of invasive breast cancer treated at our institute between January 2014 and December 2020 was done after obtaining approval from the Institute Ethics Committee (IEC). The number of patients seen, age, parity, menopausal status, family history of cancer, laterality, site of tumour in the breast, the symptomatology, clinical stage and presence or absence of metastases was the clinical parameters examined. The pathological stage and grade of the tumour, receptor status, treatment offered according to stage and the patterns of failure with respect to the surgery performed were recorded. Statistical analysis was a direct head to head comparison of the percentage proportions of the different variables. A total of 685 patients of breast cancer were treated between January 2014 and December 2020. A total of 53% of the cohort was more than 45 years old and 56.7% were post menopausal. A total of 58.8% of the patients presented with a cancer in the left breast and in the upper outer quadrant. Nearly 41% of the tumours were more than 4 cm in size. The most common receptor profile in our patient population was ER positive, PR positive and HER 2 negative. A total of 27.7% of the patients were offered neo-adjuvant chemotherapy and 63.06% underwent upfront surgery. A total of 19.7% of all surgeries performed (overall) were breast conservation surgeries (BCS). The use of BCS showed an increasing trend over the 7 years studied rising from 16.79 to 25% (annually). The local failure rate for BCS was 11.8% but the incidence of distant metastases was not significantly different compared to the patients who underwent a mastectomy. Breast conservation is safe and feasible in a referral setting even in a middle income nation with multi-disciplinary treatment planning and needs to be adopted widely to preserve the body image and self esteem of patients with breast cancer.
