Breast cancer is the mostly seen malignancy of women. Breast cancer causes lung, bone, liver and brain metastasis. On the other hand, gastric metastasis of breast cancer is a rarely seen metastasis. For this reason, it may be misdiagnosed or diagnosed after its morbid or mortal complications occurred. This may also result as a delay of breast cancers primary treatment. If occurred the best tool is immunohistochemical panels especially gross cystic disease fluid protein 15 (GCDFP-15) for exact diagnosis. In our case, a gastric metastasis of breast cancer is presented which was admitted with the acute abdominal findings caused by its result as gastric perforation and diagnosed by GCDFP-15 immunohistochemical panel.

The COVID‐19 pandemic has challenged the health systems worldwide. Because of high volume of COVID‐19 patients, all hospitals in our region were re‐configured as COVID‐19 centres and elective surgery procedures were cancelled. Our clinic was the only active centre in the region and grave increase in our patient volume urged our clinic to modify our discharge protocol. This retrospective study included all breast cancer patients underwent mastectomy and/or axillary dissection, in the Breast Surgery Clinic of Kocaeli State Hospital, a regional pandemic hospital, between December 2020 and January 2021. Patients were mostly discharged the day of surgery with drains because of congestion, while some of the patients had traditional stay, when beds were available. The patients were evaluated postoperatively (the first 30 days) in terms of wound complications, Clavien‐Dindo classification grade, satisfaction, presence of pain and nausea, and treatment costs during the follow‐up period of the study. Outcomes were compared between early discharged patients and patients who had traditional long stay. Compared with long‐stay patients, in the early discharged group, postoperative wound complications was significantly lower (P < .01) with significant cost savings. There were no significant changes in variables such as surgery type, ASA class, satisfaction, need for additional medication and Clavien‐Dindo between the groups. Adaptation to an early discharge protocol for breast cancer surgeries may be an efficient way of practicing surgery in a pandemic. Early discharge with drains may be beneficial for patients.

Objective: The involvement of axillary lymph nodes plays a key role in breast cancer staging. Positron emission tomography is a promising modality for detecting axillary lymph node metastasis. In addition, nomograms are used to predict the status of axillary lymph nodes. In this study, the role of positron emission tomography in determining axillary metastasis and its correlation with the nomogram was evaluated. Material and Methods: The axillary maximum standard uptake value (SUVmax) values of the patients in the preoperative period, the features in the perioperative and postoperative specimen and Memorial Sloan Kettering Cancer Center nomogram data were evaluated. Results: As axillary SUVmax detected by Positron emission tomography in the preoperative period increased, so did the likelihood of lymph node involvement. Axillary SUVmax value were compared with Memorial Sloan Kettering Cancer Center nomogram data but no correlation was found. Age, lymph node number, histopathology results, mass diameter, presence or absence of lymphovascular invasion and/or perineural invasion, tumor type, estrogen receptor status, Ki67 and Cerb-B2 statuses were not correlated. However, axillary SUVmax was inversely correlated with grade and progesterone receptor status. Conclusion: Results from positron emission tomography of axillary lymph nodes in breasts cancer patients showed that SUVmax was only inversely related to cancer grade and progesterone receptor status while not correlating with other accepted parameters for tumor assessment. Thus there is insufficient reliability for the use of axillary SUVmax alone for accurate assessment of tumor characteristics at present.
