ABSTRACT
In this study, we aimed to compare the surgical volume and outcomes between this COVID-19 period and data from non-COVID-19 period of last year. A retrospective observational study was done in one single surgical unit of a dedicated oncology center in a peripheral location in India. The comparison was done between patients undergoing major cancer surgery during the COVID-19 pandemic period of 1st April to 30th June 2020, when a nation-wide lockdown was in force, to a comparable period of last year. Statistical analysis was done using SPSS software 20.0. A total of 72 patients underwent major cancer surgery during this period, with surgery for breast cancer (n = 26) being the major sub-site operated. This was a significant decrease from the total 209 major cancer surgeries performed during a similar period of last year (2019) (p < 0.05). There were several reasons for the decrease in surgical numbers, including the difficulty in travel and accommodation during the lockdown period. The mean distance of patient's residence from the treating hospital was 45.7 km (range 4 to 165 km). Public transport was in a limbo and inter-state travel was restrictive with mandatory quarantine rules in effect. Morbidity associated with major surgeries was observed to be significantly less during the COVID-19 period compared to the pre-COVID-19 times (8.3% vs 17.2% with a p value of < 0.05), which can probably be attributed to the lesser number of complex surgical procedures being performed. There was no significant difference between the total mortality percentages (2.8% vs 3.8%). A total of 156 PPE kits were used (3-4/per patient) throughout the in-hospital care of the surgical patients included in this study. In the midst of a pandemic, the delivery of surgical cancer care is an essential service and although the surgical volume is significantly hampered due to various reasons, the outcomes are largely unaffected.
ABSTRACT
Objective The aim of the study is to see the prevalence of different molecular subtypes in breast cancer patients among two different age groups: ≤40 years and >40 years. Materials and Methods Retrospective study was conducted from January 2019 to December 2019. We studied 568 cases of breast carcinoma and classified them into four molecular subtypes-luminal A, luminal B, human epidermal growth factor-2 (HER 2), and triple negative. Cases were divided into two different groups: (1) ≤40 years and (2) >40 years. Statistical Analysis was done by using SPSS software version 20.0. Results Out of 568 cases, 151 (26.6%) were ≤40 years of age and 417 (73.4%) were >40 years of age. The most common histological subtype of breast cancer was ductal carcinoma in 548 cases and the most common grade was grade III. Immunohistochemistry was done in 432 patients. In younger age group, the most common molecular subtype was luminal B (31%) followed by triple negative (20%), luminal A (14%), and then HER 2 (5.3%), while in the older age group most common molecular subtype was luminal B (27.8%) followed by triple negative (14%), HER 2 (12.2%), and then luminal A (12%). Conclusion Luminal B is found to be the most common subtype in Northeast Indian women with breast cancer, as compared with other studies in which luminal A was the most common subtype. This could be due to the reason that K i -67 was not done in most of the other studies.
