Aim   To evaluate the safety issues and adverse effects of using TCHP regimen (docetaxel, carboplatin, trastuzumab, and pertuzumab) versus TCP regimen (docetaxel, carboplatin, and trastuzumab) in older postmenopausal women with nonmetastatic HER2-positive breast cancer. HER2 overexpressed in 20–25% of breast cancer signals an aggressive form of breast cancer and is treated with trastuzumab and pertuzumab.Methods   The patient record database was accessed to identify all postmenopausal women in the Punjab Care hospital who were above 65 years old, with stages 1–3 HER2-positive breast cancer and treated with neoadjuvant TCHP and neoadjuvant TCP from 2013 till 2016.Results   In TCH-P group and TCH group, mild fatigue (34% versus 36%) and diarrhea (48% versus 49%) were most common toxicities. Fever in TCH-P group and TCH group (12% versus 13%) was common. Anorexia affected 21% and 16% of patients receiving TCH and TCHP regimen, respectively. Febrile neutropenia was higher in TCH-P group 13% (3/23) versus 4.5% (1/22) in TCH group. Also 27.2% (6/22) of TCH-P group was hospitalized for treatment related toxicities versus 21.7% (5/23) of TCH group.Conclusion   Comparing neoadjuvant TCP and neoadjuvant TCH-P showed TCH-P regimen had an acceptable toxicity profile. Severe cardiac dysfunction was not observed. Using TCH-P regimen can be considered as relatively safe therapeutic option for elderly postmenopausal women with nonmetastatic HER2-positive breast cancer.
