Objective: The coronavirus-2019 (COVID-19) pandemic caused delaying breast cancer management, increasing time interval in chemotherapy cycles and surgery. This has implications on radiological manifestation of cancer. Further, we evaluated changes observed in mammography.
Materials and Methods:This case control study was conducted from March 25 th , 2020 to August 15 th , 2020 at the Integrated Breast Care Centre, All India Institute of Medical Science Rishikesh (AIIMS), Rishikesh. Sonomammography was performed on follow-up patients who were on chemotherapy and were scheduled for surgery. Moreover, duration of delay from the last neoadjuvant chemotherapy (NACT) cycle was recorded. Similar data in the pre-COVID-19 period from November 4 th , 2019 to March 24 th , 2020 was compared with post-COVID-19 data and was analyzed by SPSS Version 23.
Results:The study included 54 patients who presented between March 25 th , 2020 and August 15 th , 2020. Furthermore, the delay in NACT cycles has been shown to be associated with disease progression (p = 0.045). Subgroup analysis of treatment duration with various parameters revealed significant correlation between size, appearance of ulceration, and response evaluation (p<0.05). However, no significant association was found between duration of delay and the histological subtype of lesion (p>0.05). A substantial difference was seen in the evaluation of NACT response in pre-and post-COVID-19 time, with partial response (n = 39, 58.24%) seen as the most common response in pre-COVID-19 time and progressive disease (n = 28, 51.9%) as the most common response in post-COVID-19 time (p<0.001).
Conclusion:The coronavirus pandemic has severe impact on breast cancer management. A delay in NACT causes progression in cancer. This can be seen in ultrasound and mammogram.
Objective:
We conducted this study to understand the factors that contribute to the delay in diagnosis of symptomatic breast cancer patients.
Methodology:
We did a prospective analytical study with both quantitative and qualitative components over 14 months. The total delay in diagnosis of breast cancer from first symptom onset was defined as diagnostic delay. Presentation delay was defined as the time duration between the first symptom and the first visit to a health care provider. Provider delay was defined as the time duration between the presentation to a health care provider and the final diagnosis. Three hundred female breast cancer patients with a diagnostic delay of at least 3 months were interviewed using a pre-tested semi-structured questionnaire.
Results:
We found that more than 50% of patients with delayed presentation were between 30-50 years of age. Painless breast lump was the most common initial symptom. More than 70% of patients presented with locally advanced and metastatic disease. The patient-related delay was more common than provider delay. Breast cancer awareness (p = 0.040) and reasons for delay (p = 0.014) were found to significantly influence the delay. More than 70% of patients reported their symptoms to male members of their families.
Conclusion:
Breast cancer awareness is the single most important determinant influencing diagnostic delay among symptomatic patients.
Metastatic breast cancer cells carry adult and neonatal variants of NaV1.5 voltage-gated activated Na
+
channels involved in cell invasion. We hypothesize that instilling lignocaine near the surgical field to anesthetize the pectoral nerves for analgesia will decrease angiogenesis by blocking voltage-gated activated Na
+
channels. Twenty patients undergoing unilateral modified radical mastectomy were randomized in a single-blinded, parallel-arm group feasibility pilot study in two groups. In Group I a catheter was placed between the pectoralis major and minor muscle under direct vision before skin closure. Ten milliliters of 2% lignocaine was given as an initial bolus followed by 10 mL of 2% lignocaine every 8 hours up to 24 hours. Group II did not receive any regional block. Primary measure outcomes were pre and postoperative changes in levels of vascular endothelial growth factor. Secondary outcomes were postoperative pain scores and total rescue analgesia used. Nine patients in each group were analyzed. Baseline demographic data of all females were similar with respect to age, body mass, height and duration of anesthesia. Postoperative mean serum levels of vascular endothelial growth factor were decreased by 46.60% from baseline in Group I, while were increased by 84.27% as compared to preoperative values in Group II. Postoperative average pain scores were less in Group I. Postoperative rescue analgesia in 24 hours in Group I was lower than that in Group II. There was no postoperative adverse event related to catheter or lignocaine administration at given doses. Instilling lignocaine to block pectoral nerves provides better postoperative analgesia and decreases a marker of angiogenesis. The study protocol was approved by the Institutional Ethical Committee of the Tertiary Centre (All India Institute of Medical Sciences Rishikesh India) (No. AIIMS/IEC/19/1002) on August 9, 2019, and the larger expansion trial was prospectively registered on Clinical Trial Registry India (No. CTRI/2020/01/022784) on January 15, 2020.
