Intervention for Hepatic and Pulmonary Metastases in Breast Cancer Patients: Prospective, Multi-institutional Registry Study-IMET, Protocol MF 14-02.

BACKGROUND: One fourth of early-stage breast cancer cases become metastatic during the follow-up period. Limited metastasis is a metastatic disease condition in which the number of metastatic sites and the extent of the disease both are limited, and the disease is amenable to metastatic intervention. This prospective study aimed to evaluate intervention for limited metastases in the lung, liver, or both. METHODS: The study enrolled luminal A/B and/or human epidermal growth factor receptor 2 (HER2)-neu+ patients with operable lung and/or liver metastases in the follow-up assessment after completion of primary breast cancer treatment and patients with a diagnosis of metastasis after 2014. Demographic, clinical, tumor-specific, and metastasis detection-free interval (MDFI) data were collected. Bone metastasis in addition to lung and liver metastases also was included in the analysis. The patients were divided into two groups according to the method of treatment for metastases: systemic therapy alone (ST) group or intervention (IT) group. RESULTS: Until June 2020, 200 patients were enrolled in the study. The demographic data were similar between the two groups. The median follow-up time was 77 months (range 55-107 months) in the IT group (n = 119; 59.5%) and 57 months (range 39-84) in the ST-only group (n = 81; 40.5%). The median MDFI was 40 months (range 23-70 months) in the IT group, and 35 months (range 13-61 months) in the ST-only group (p = 0.47). The groups had similar surgeries for the primary tumor and axilla. Most of the patients had liver metastases (49.5%, n = 99), and 42% (n = 84) of the patients had lung metastases. Both lung and liver metastases were found in 8.5% (n = 17) of the patients. The primary tumor was estrogen receptor/progesterone receptor-positive in 75% (n = 150) of the patients, and 32% (n = 64) of the patients had HER2-neu+ tumors. Metastatic-site resection was performed for 32% (n = 64) of the patients, and 27.5% (n = 55) of the patients underwent metastatic ablative interventions. In the Kaplan-Meier survival analysis, the hazard of death (HoD) was 56% lower in the IT group than in the ST-only group (hazard ratio [HR], 0.44; 95% confidence interval [CI] 0.26-0.72; p = 0.001). The HoD was lower in the IT group than in the ST-only group for the patients younger than 55 years (HR, 0.32; 95% CI 0.17-0.62; p = 0.0007). In the multivariable Cox regression model, HoD was significantly lower for the patients who underwent intervention for metastases and had an MDFI longer than 24 months, but their liver metastases doubled the risk of death compared with lung metastases. CONCLUSION: Metastasis-directed interventions have reduced the risk of death for patients with limited lung/liver metastases who are amenable to interventions after completion of primary cancer treatment. For a select group of patients, such as those with luminal A/B or HER2-neu+ breast cancer who are younger than 55 years with limited metastases to the lung and liver or an MDFI longer than 24 months, surgical or ablative therapy for metastases should be considered and discussed on tumor boards.

Quality of life after thyroid surgery.

PURPOSE: The purpose of this study was to inquire how patients' quality of life is affected after thyroid surgery and the factors involved. METHODS: A semi-structured questionnaire and the World Health Organization Quality of Life Scale (WHOQOL-BREF) were applied to 101 patients prior to surgery. Thereafter data was collected in the early and again in the late post-operative period. RESULTS: Mean general health score for pre-operative quality of life was 6.72 ± 1.53 (3-10), mean physical field score was 22.81 ± 2.77 (17-31), mean psychological field score was 21.69 ± 2.78 (15-28), mean social field score was 11.10 ± 1.94 (5-15) and mean environmental field score was 27.86 ± 4.30 (18-39). In the early post-operative period, mean general health score was 7.05 ± 1.45 (4-10), mean physical field score was 22.84 ± 2.83 (14-29), mean psychological field score was 21.67 ± 2.32 (16-27), mean social field score was 10.89 ± 1.96 (5-15) and mean environmental field score was 28.56 ± 4.18 (18-40). In the late post-operative period, the general health score for quality of life was 7.43 ± 1.34 (4-10), mean physical field score was 23.59 ± 2.70 (17-35), mean psychological field score was 21.75 ± 2.34 (14-29), mean social field score was 11.23 ± 1.94 (6-15) and mean on-field environment score was 29.30 ± 3.96 (16-40). The pre-operative levels of symptoms were found to be higher than early and late post-operative periods. CONCLUSIONS: Quality of life increased after total thyroidectomy and statistically significant improvement was observed in late post-operative stage.

The effect of internal mammary lymph node biopsy on the therapeutic decision and survival of patients with breast cancer.

BACKGROUND: The role of internal mammary lymph node biopsy (IMLNB) is still being discussed in breast cancer treatment. The aim of this study was to investigate the role of IMLNB on adjuvant therapy and survival of patients with breast cancer. PATEINTS AND METHODS: The data of 72 patients with clinically negative axilla and IMLNB were evaluated. IMLNB was performed either through a small separate intercostal incision or from the same incision for tumor resection or mastectomy by using both blue dye and radioisotope. Pathological analysis was performed on formalin-fixed paraffin-embedded tissues. RESULTS: Ten of the patients (14%) were IMLNB-positive. The axillary sentinel lymph node and IMLN were negative in most of the patients (52.8%). In one patient (1.4%), the axilla was negative but the IMLNB was positive. IMLNB changed the pathologic stage in eight patients (11%). Adjuvant internal mammary radiotherapy was added to the treatment protocol for 10 patients due to IMLNB positivity and adjuvant chemotherapy was added in for only one patient with negative axilla. The factors found to be related with IMLN positivity were SLN positivity (p = 0.033), mastectomy (p = 0.022), and the number of resected IMLN ≥2 (p = 0.040). The median follow-up time was 115.5 months (range, 30-162 months). The ten-year overall survival (OS) rate was 86%. Systemic metastasis (p = 0.007), SLNB positivity (p < 0.001), and IMLNB positivity (p = 0.005) were statistically related to overall survival. CONCLUSION: IMLNB positivity in patients with breast cancer changed the pathologic stage and adjuvant treatment modalities of patients and also adversely affected the overall survival.

Positive or close margins in breast conserving surgery: is re-excision always necessary?

BACKGROUND: More than half of re-excision specimens after breast conserving surgery (BCS) are found to be free of residual tumor at definitive histology. The aim of this study was to identify clinicopathological factors along with intrinsic subtypes of the tumor (luminal A, luminal B, HER2-overexpressing, triple-negative) associated with residual tumor in re-excision or mastectomy specimen. METHODS: Two hundred forty-eight patients with initial BCS, who underwent one or more re-excisions or mastectomy because of close or positive margins were reviewed. RESULTS: Residual cancer was found in 50% of re-excision(s) or mastectomy specimens. Patients with multifocality (vs unifocality; OR = 5.2; 95% CI, 2.6-10.4) or positive nodes (vs negative nodes; OR = 2.5; 95% CI, 1.4-4.4), or positive margins (vs close margins; OR = 1.7; 95% CI = 1.0-2.9) were more likely to have residual tumor in re-excision or mastectomy specimen compared to others. CONCLUSION: Our results suggest that further surgery is often indicated in patients with node positive or multifocal cancers or positive margins after BCS since residual disease cannot be ruled out. Re-excision or mastectomy could be omitted in patients with close margins with favorable factors such unifocal tumor or node negative disease.

Selective conservative management of penetrating hollow viscus injuries: a report of three cases.

In this manuscript, we report three cases of penetrating abdominal injury: one with pellet injury, one with pellet injury after a bomb explosion and one with gunshot injury. All three patients were successfully managed nonoperatively. A 30-year-old male was admitted to our trauma and emergency service with a pellet injury. His physical examination revealed multiple pellet injuries in the left upper abdominal quadrant, left hemithorax, left axilla, dorsal side of the abdomen, left upper extremity, and left gluteus. The second case was a 16-year-old male admitted with a shrapnel injury after a bomb explosion. His physical examination revealed multiple shrapnel injuries in the thoracal and abdominal regions, extremities and left eye. The third case was a 30-year-old male admitted with gunshot and stab wound injury. He had multiple stab wound injuries in both lower extremities and a gunshot wound in the left posterosuperior hemithorax, left upper abdomen and left dorsolumbar region. All these cases were treated non-operatively. We advocate a policy of selective conservatism based on careful initial and subsequent serial clinical examinations and imaging techniques as needed.

Axillary sentinel node biopsy after neoadjuvant chemotherapy.

INTRODUCTION: The role of sentinel lymph node biopsy (SLNB) in patients with locally advanced breast cancer (LABC) with potentially sterilized axillary lymph nodes after neoadjuvant chemotherapy (NAC) remains unclear. PATIENTS AND METHODS: Between 2002 and 2008, SLNB with both blue-dye and radioisotope injection was performed in 77 patients with LABC whose cytopathologically confirmed positive axillary node(s) became clinically negative after NAC. Factors associated with SLN identification and false-negative rates, presence of non-sentinel lymph node (non-SLN) metastasis were analyzed retrospectively. RESULTS: SLNB was successful in 92% of the patients. Axillary status was predicted with 90% accuracy and a false-negative rate of 13.7%. Patients with residual tumor size >2 cm had a decreased SLN identification rate (p=0.002). Axillary nodal status before NAC (N2 versus N1) was associated with higher false-negative rates (p=0.04). Positive non-SLN(s) were more frequent in patients with multifocal/multicentric tumors (versus unifocal; p=0.003) and positive lymphovascular invasion (versus negative; p=0.0001). SLN(s) positive patients with pathologic tumor size >2 cm (versus 2 cm, and extra-sentinel node extension.
