In this study we compared radiation dose received by organs at risk (OARs) after breast conservation surgery(BCS) and mastectomy in patients with left breast cancer.

Total 30 patients, 15 each of BCS and mastectomy were included in this study. Planning Computerised Tomography (CT) was done for each patient. Chest wall, whole breast, heart, lungs, LAD, proximal and distal LAD, and contra lateral breast was contoured for each patient. Radiotherapy plans were made by standard tangent field. Dose prescribed was 40Gy/16#/3 weeks. Mean heart dose, LAD, proximal and distal LAD, mean and V5 of right lung, and mean, V5, V10 and V20 of left lung, mean dose and V2 of contra lateral breast were calculated for each patient and compared between BCS and mastectomy patients using student’s T test.

Mean doses to the heart, LAD, proximal LAD and distal LAD were 3.364Gy, 16.06Gy, 2.7Gy, 27.5Gy; and 4.219Gy, 14.653Gy, 4.306Gy, 24.6Gy, respectively for mastectomy and BCS patients. Left lung mean dose, V5, V10 and V20 were 5.96Gy, 16%, 14%, 12.4%; and 7.69Gy, 21%, 18% and 16% in mastectomy and BCS patients, respectively. There was no statistical significant difference in the doses to the heart and left lung between mastectomy and BCS. Mean dose to the right lung was significantly less in mastectomy as compared to BCS, 0.29Gy vs. 0.51Gy, respectively (p = 0.007). Mean dose to the opposite breast was significantly lower in patients with mastectomy than BCS (0.54Gy Vs 0.37Gy, p = 0.007). The dose to the distal LAD was significantly higher than proximal LAD both in BCS (24.6Gy Vs 4.3Gy, p = <0.0001) and mastectomy (27.5Gy Vs 2.7Gy, p = <0.0001) patients.

There was no difference in doses received by heart and left lung between BCS and mastectomy patients. Mean doses to the right lung and breast were significantly less in mastectomy patients.

Mastectomy is a treatment option for patients diagnosed with breast cancer. There is very limited research into the psychosocial impact of mastectomy on female breast cancer patients, especially in the sub-Saharan African setting which has unique cultural norms. The study aimed at assessing the psychosocial impact of mastectomy on female breast cancer patients attending a radiotherapy/oncology centre in Ghana.

A cross-sectional design was used to undertake this study. A total of 80 female mastectomy breast cancer patients participated in this study. A semi-structured questionnaire was used for data collection over a 5-month period, January to May 2018. The data collected were analysed with Statistical Package for Social Science (SPSS) version 22.

Most of the participants were adversely affected psychologically and emotionally by mastectomy. In particular, many (56·7%) agreed that they felt less feminine, and 71% reported they experienced psychological distress as a result of their mastectomy, while 63% of them reported loss of self-confidence. A large proportion of them (51, 63·8%) agreed that their lifestyles had changed following mastectomy, while 58% of them admitted that they felt treated as outcasts by society, and 75% resorted to the use of breast prostheses to reduce attention.

The study revealed that mastectomy for breast cancer patients had a negative impact on their psychological, emotional and social well-being. The availability of affordable breast prostheses, involvement of clinical psychologists in the care of post-mastectomy women, provision of emotional, psychological and even financial support could alleviate the psychosocial impact of affected women.

Social support has been reported as beneficial for the psychological functioning of people coping with a disease. The objective of this study was to verify whether levels of perceived social support are associated with psychosocial functioning in women who have had a mastectomy and whether specific types of social support are linked to specific indices of functioning.

Seventy women with a history of mastectomy completed questionnaires measuring their psychosocial functioning as related to their health status: Disease-Related Appraisal Scale, Acceptance of Life with the Disease Scale and Beck Depression Inventory. All participants also completed a measure of perceived social support (Disease-Related Social Support Scale).

Women who reported higher levels of perceived social support revealed statistically significantly lower levels of depressive symptoms, higher appraisals of their disease in terms of challenge and value, and lower appraisals of their disease in terms of obstacle/loss. Women with greater social support also revealed higher levels of acceptance of life with the disease compared to those with less social support. Regression analyses showed that spiritual support was the type of support that significantly accounted for the variance in the majority of functioning indices. Some indices of functioning were also significantly accounted for by emotional and instrumental support.

The process of psychological adjustment to a life-threatening disease such as breast cancer depends on multiple variables; however, social support, including spiritual support, seems to be one significant contributor to this process.

To observe the impact of internal mammary node irradiation (IMNI) on disease-free survival (DFS) and overall survival (OS) in postmastectomy women with breast cancer.

Between 1978 and 1996, 153 women with stage II–III breast cancer were treated with postmastectomy radiation therapy (RT) with IMNI. Their clinical, pathological and treatment characteristics were matched with 166 patients without IMNI. The RT dose was 35 Gy to the chest wall and 40 Gy to the supraclavicular fossa and IMN in 15 fractions over 3 weeks with photons. All patients were planned with two-dimensional technique. Adjuvant chemotherapy was administered to 41% and endocrine therapy to 52% of the patients. Symptomatic patients were further assessed for late pulmonary and late cardiac effects.

The median follow-up period was 203 months (range, 182–224), and the median age was 44 years (range 20–73 years). The IMNI group had significantly more right-sided and inner/central quadrant tumours. Other characteristics were comparable between both the groups. DFS at 15 years with and without IMNI was 64 and 49%, respectively (p=0·0001). On multivariate analysis, IMNI was an independent, positive predictor of DFS [hazard ratio (HR), 2·89; p=0·0001]. Benefit of IMNI on DFS was more apparent in inner/central tumours [HR, 1·48; 95% confidence interval (CI), 1·02–2·88], N2–N3 patients (HR, 1·44; 95% CI, 1·09–2·10) and in those who received chemotherapy (HR, 1·70; 95% CI, 1·07–2·71). OS at 15 years with and without IMNI was 68 and 54%, respectively (p=0·0001). Late pulmonary toxicity was 1·5 versus 1% with and without IMNI, respectively. Late cardiac toxicity was 2·6 versus 1·8% with and without IMNI, respectively.

IMNI significantly improved DFS and OS in postmastectomy breast cancer patients. Benefit of IMNI was seen in patients with central/inner tumours and N2–N3 disease. Late cardiopulmonary toxicities were comparable between the two groups.
