COVID-19 Impact on Newly Diagnosed Breast Cancers at Regional Cancer Centre, Thiruvananthapuram-An Audit.

Geethu Babu The coronavirus pandemic has created havoc in every aspect of life including cancer care and was declared a pandemic. This audit was conducted to study the impact of the pandemic on diagnosis and treatment of newly diagnosed breast cancer patients at a tertiary cancer center in South India. A total of 1,647 patients who registered at Regional Cancer Centre (RCC), Thiruvananthapuram, Kerala, India for breast cancer during the period April 1, 2020, to September 30, 2020 (COVID-19 period) as well as April 1, 2019, to September 30, 2019 (pre-COVID-19 period) were included in the study. Data regarding the geographic distribution, stage at presentation, time factors for reporting for care, diagnosis, and treatment, referral for care elsewhere were collected and analyzed. The study was approved by the Institutional Review Board. Means and ranges were calculated for continuous type variables, and numbers and percentages for categorical variables. To determine whether there were significant differences between the two groups, independent t -test was used for continuous variables and chi-square test for categorical type of variables. A notable reduction (36%) in newly diagnosed breast cancer patients was seen in 2020 when compared with 2019. There was a significant difference in the geographic distribution of patients in both cohorts ( p = 0.001) and a notable reduction in the number of patients reporting to RCC for treatment from the northern districts of Kerala (81%) and outside Kerala (89.5%). There was no significant difference in the time (in weeks) since symptom onset and reporting to hospital or the clinical stage at diagnosis between the groups. Also, coronavirus disease 2019 (COVID-19) did not seem to negatively impact time intervals between date of registration and pathological diagnosis or start of primary treatment. More patients received neoadjuvant systemic therapy during 2020 compared with 2019, and this difference was statistically significant ( p = 0.004). There was no difference in the type of surgery (breast-conserving surgery vs. modified radical mastectomy). The results demonstrate that COVID-19 did not appear to negatively impact the diagnosis and treatment of newly diagnosed breast cancer patients. However, this is largely attributable to the significantly less number of patients who registered, for whom the departments were able to maintain timely cancer care despite the difficult pandemic times. Significantly more patients received neoadjuvant systemic therapy in 2020.

Taxane-induced acute interstitial pneumonitis in patients with breast cancer and outcome of taxane rechallenge.

Background: Although rare, taxane-induced interstitial pneumonitis is a well-recognized toxicity following chemotherapy. Data on taxane rechallenge in patients who developed taxane-induced interstitial pneumonitis following chemotherapy are limited. Here, we share our experience of acute interstitial pneumonitis following taxane chemotherapy for breast cancer and its clinical outcome following steroids and subsequent rechallenge with taxanes in selected patients without residual lung abnormalities on imaging following steroid treatment. Objectives: To study the taxane-induced acute interstitial pneumonitis in patients with breast cancer receiving chemotherapy and outcome of taxane rechallenge in these patients. Materials and Methods: Patients with breast cancer who developed taxane-induced acute interstitial pneumonitis following chemotherapy either with paclitaxel or docetaxel were included. Results: Among 1240 patients with breast cancer, who received chemotherapy with either docetaxel or paclitaxel, 41 patients developed taxane-induced acute interstitial lung disease (ILD) during the study period. The interstitial pneumonitis was more seen with docetaxel. Among paclitaxel regimens, weekly schedules showed more cases of ILD than 2 weekly paclitaxel. After steroid pulse/maintenance treatment, complete resolution of lung abnormalities was seen in 76%, but residual interstitial pattern on imaging was noted in 24% of patients. Taxane rechallenge was done in 20 (49%) patients. Agents used were paclitaxel, nab-paclitaxel, or docetaxel. All rechallenged patients received short-course oral steroids for one week following taxane rechallenge as a safety measure. Rechallenge was not done in 51% either due to patient unwillingness for rechallenge (27%) or patient with residual interstitial pattern on imaging (24%). None of the patients experienced any recurrence of pneumonitis or any mortality following taxane rechallenge. Conclusion: Acute interstitial pneumonitis is a well-known toxicity following taxanes in breast cancer and taxane rechallenge is an option in those patients without any residual pneumonitis following steroid pulse/maintenance. We also advise short-course oral steroids for 1 week following taxane rechallenge as a safety measure. We strongly do not recommend rechallenge in patients with residual lung abnormalities after steroids.

Bilateral synchronous plasmacytoma of the testis.

Extramedullary plasmacytoma (EMP) is usually seen in the head and neck regions and in the upper respiratory, gastrointestinal, and central nervous systems. Testis is a rare site for EMP, and bilateral synchronous testicular plasmacytoma occurring as an isolated event at initial presentation has been reported only once previously. We present herein the second such report in a 70-year-old man who underwent bilateral orchidectomy.
