A Comprehensive Analysis of Neoadjuvant Chemotherapy in Breast Cancer: Adverse Events, Clinical Response Rates, and Surgical and Pathological Outcomes-Bozyaka Experience.

To evaluate the neoadjuvant chemotherapy (NACTx) process in breast cancer (BC), its significant treatment-related adverse events (trAEs), tumor clinical response rates, and surgical and pathological outcomes, and to analyze factors influencing cavity shaving and axillary lymph node dissection (ALND) following sentinel lymph node biopsy (SLNB). A comprehensive retrospective study was conducted at a single center on patients who received NACTx for BC between 2015 and 2021. Medical records of 242 patients were reviewed.

De-Escalation of Nodal Surgery in Clinically Node-Positive Breast Cancer.

Importance: Increasing evidence supports the oncologic safety of de-escalating axillary surgery for patients with breast cancer after neoadjuvant chemotherapy (NAC).

Objective: To evaluate the oncologic outcomes of de-escalating axillary surgery among patients with clinically node (cN)-positive breast cancer and patients whose disease became cN negative after NAC (ycN negative).

Design, Setting, And Participants: In the NEOSENTITURK MF-1803 prospective cohort registry trial, patients from 37 centers with cT1-4N1-3M0 disease treated with sentinel lymph node biopsy (SLNB) or targeted axillary dissection (TAD) alone or with ypN-negative or ypN-positive disease after NAC were recruited between February 15, 2019, and January 1, 2023, and evaluated.

Breast Cancer Recurrence in Initially Clinically Node-Positive Patients Undergoing Sentinel Lymph Node Biopsy After Neoadjuvant Chemotherapy in the NEOSENTITURK-Trials MF18-02/18-03.

Background: This study aims to identify factors predicting recurrence and unfavorable prognosis in cN+ patients who have undergone sentinel lymph node biopsy (SLNB) following neoadjuvant chemotherapy (NAC).

Methods: The retrospective multi-centre "MF18-02" and the prospective multi-centre cohort registry trial "MF18-03" (NCT04250129) included patients with cT1-4N1-3M0 with SLNB+/- axillary lymph node dissection (ALND) post-NAC.

Results: A total of 2407 cN+ patients, who later achieved cN0 status after NAC and subsequently underwent SLNB, were studied.

Comprehensive Immunohistochemical Analysis of Epithelial-Mesenchymal Transition Biomarkers in the Invasive Micropapillary Cancer of the Breast.

: Invasive micropapillary carcinoma (IMPC) of the breast is commonly associated with a poor prognosis due to its high incidence of lymphovascular invasion and lymph node metastasis (LNM). Our study is aimed at investigating the prognostic significance of the expressions of E-cadherin (E-cad), N-cadherin (N-cad), CD44s, and -catenin (-cat). In addition, it is aimed at deciphering the consistency of these markers between the IMPC, the invasive breast carcinoma, no-special type (IBC-NST), and LNM components in the same IMPC cases.

HLA-B*51 Frequency in Transplant Patients and Donors.

Objectives: HLA molecules play a crucial role in transplantation. The best treatment modality in patients with end-stage renal disease is renal transplant. HLA mismatches between patients and donors can prolong time for renal transplant therapy, reduce graft survival, and increase mortality.

Pancultural nostalgia in action: Prevalence, triggers, and psychological functions of nostalgia across cultures.

Nostalgia is a social, self-relevant, and bittersweet (although mostly positive) emotion that arises when reflecting on fond past memories and serves key psychological functions. The majority of evidence concerning the prevalence, triggers, and functions of nostalgia has been amassed in samples from a handful of largely Western cultures. If nostalgia is a fundamental psychological resource, it should perform similar functions across cultures, although its operational dynamics may be shaped by culture.

The Oncologic Safety of Sentinel Lymph Node Biopsy in Patients with Node-Positive Breast Cancer with Complete Response to Neoadjuvant Chemotherapy: A Single-Center Experience.

Objective: To evaluate the efficiency and safety of sentinel lymph node biopsy (SLNB) in patients with breast cancer with complete response to neoadjuvant chemotherapy (NAC).

Methods: Ninety-two consecutive (T1-4 and N1-2) patients with breast cancer who had pathologic and/or clinical and radiologic axillary lymph node involvement were included. All patients received NAC.

Gastrointestinal Tract Metastases of Invasive Lobular Carcinoma of the Breast: An Immunohistochemical Survey Algorithm.

Invasive lobular carcinoma (ILC) accounts for almost 15% of all breast carcinomas. The potential of ILC to metastasize to the gastointestinal system is significantly greater than that of invasive ductal carcinoma. Gastric metastasis occurred in the ninth year of the follow-up in a patient who was operated on the right breast due to ILC.

The Importance of the Pathological Perspective in the Management of the Invasive Lobular Carcinoma.

Background: Invasive lobular carcinomas (ILC) account for 10-15% of all breast cancers and are the second most common histological form of breast cancer. They usually show a discohesive pattern of single cell infiltration, tend to be multifocal, and the tumor may not be accompanied by a stromal reaction. Because of these histological features, which are not common in other breast tumors, radiological detection of the tumor may be difficult, and its pathological evaluation in terms of size and spread is often problematic.

The effectiveness and safety of neoadjuvant pertuzumab and trastuzumab in women with locally advanced, inflammatory, or early-stage human epidermal growth factor receptor 2-positive breast cancer: Turkish Oncology Group study.

In our study, we aimed to evaluate the pathological response rates and side effect profile of adding pertuzumab to the treatment of HER2+ locally advanced, inflammatory, or early-stage breast cancer. This study was conducted by the Turkish Oncology Group (TOG) with data collected from 32 centers. Our study was multicentric, and a total of 364 patients were included.

Prognostic Value of Receptor Change After Neoadjuvant Chemotherapy in Breast Cancer Patients.

Objective: The aim of this study was to investigate the relationship between hormone receptors (HR) and human epidermal growth factor receptor 2 (HER-2) discordance with prognosis, before and after neoadjuvant chemotherapy (NAC) in breast cancer patients.

Materials And Methods: Histopathological data of 142 breast cancer patients attending a single center between 2001 and 2018 and were operated after NAC were evaluated retrospectively.

Results: The median (range) age of patients was 58 (32-69) years.

Genitourinary Cancers Following Kidney Transplant: Our 20 Years of Experience With Mechanistic Target of Rapamycin Inhibitors.

Objectives: We investigated patients with genitourinary cancer after kidney transplant and the effects of immunosuppression reduction and switching to mechanistic target of rapamycin inhibitors.

Materials And Methods: We retrospectively evaluated kidney transplant recipients seen at our center between January 2000 and January 2020. Patients with <1 year of follow-up were excluded.

Favorable outcome with sentinel lymph node biopsy alone after neoadjuvant chemotherapy in clinically node positive breast cancer at diagnosis: Turkish Multicentric NEOSENTI-TURK MF-18-02-study.

Purpose: Factors affecting local outcome were evaluated in patients with clinically node-positive (cN+) breast cancer at diagnosis, who underwent sentinel lymph node biopsy (SLNB) alone after neoadjuvant chemotherapy (NAC).

Methods: Between 2004 and 2018, 303 cytopathology-proven cN (+) patients in a multicentric registry, who received NAC and underwent SLNB alone were analysed. All patients had regional nodal irradiation.

COVID-19 pneumonia in kidney transplant recipients: A promising treatment algorithm in the absence of a disease-specific drug.

There is no consensus on the management of coronavirus disease 2019 (COVID-19) and modification of immunosuppressive therapy in kidney transplant recipients (KTRs). In this study, we examined the clinical outcome of our KTRs with COVID-19 disease, who were treated with a broad-spectrum anti-inflammatory protocol. This protocol is essentially composed of intravenous immunoglobulin +/- tocilizumab in KTRs with severe COVID-19 pneumonia.

Clinicopathologic features of single bone metastasis in breast cancer.

The most common site for metastasis in patients with breast cancer is the bone. In this case series, we investigated patients whose surgical and medical treatment for primary breast cancer was conducted at our center and first disease recurrence was limited to only 1 bone.We analyzed 910 breast cancer patients, 863 had no metastasis and 47 cases had a single bone metastasis ≥ 6 months after their first diagnosis.

Acute lower gastrointestinal bleeding due to low-grade mucinous neoplasm of appendix.

Introduction: Lower gastrointestinal tract (GIT) bleeding originating from the appendix is rare and may be difficult to diagnose.

Patients And Methods: In this case report, we present an 88-year-old male patient who was admitted with hematochezia due to appendiceal bleeding. A colonoscopy revealed bleeding in the appendix orifice so an appendectomy was performed, and bleeding did not recur in the postoperative period.

Survival outcomes after D1 and D2 lymphadenectomy with R0 resection in stage II-III gastric cancer: Longitudinal follow-up in a single center.

Objective: D2 lymphadenectomy (D2-LND) with curative resection (R0) is the cornerstone of gastric cancer treatment. In this study, we compared survival outcomes of D2-LDN with D1-LDN in patients who had undergone curative resection for Stages II and III primary gastric adenocarcinoma.

Material And Methods: Between April 1996 and March 2014, 153 consecutive patients with adenocarcinoma of the stomach underwent total gastrectomy with D1-LND or D2-LND.

The waxing and waning of mnemic neglect.

The mechanisms underlying mnemic neglect (MN) and the conditions under which it waxes and wanes are not yet fully understood. The research in this article examined conditions during both encoding and recall that could potentially moderate the MN effect and that could provide cues about the cognitive mechanisms that contribute to the effect. Results showed that MN: (a) emerged after recall was delayed (Study 1); (b) could not be attributed to differential behavior looking time (Study 2); (c) did not emerge under cognitive load (Study 3); and (d) was not linked to the perceived extremity, importance, or evaluations of the behaviors.

Preparation of Tc-isosulfan blue for lymph node localization in rats Tc-isosulfan blue for lymph node localization.

The sentinel lymph node (SLN) is defined as the first regional lymph node to receive lymphatic drainage from a malignant tumor. Therefore, this node is a "sentinel" for second metastatic lymph node stations and for labeling regional tumor spread. For SLN detection, many surgeons preferred a combination of a preoperative injection of radiolabeled colloid and the intraoperative injection of blue dye.

An exploration of the relationship among valence, fading affect, rehearsal frequency, and memory vividness for past personal events.

The affect associated with negative (or unpleasant) memories typically tends to fade faster than the affect associated with positive (or pleasant) memories, a phenomenon called the fading affect bias (FAB). We conducted a study to explore the mechanisms related to the FAB. A retrospective recall procedure was used to obtain three self-report measures (memory vividness, rehearsal frequency, affective fading) for both positive events and negative events.

Spontaneous trait inference and spontaneous trait transference are both unaffected by prior evaluations of informants.

This article reports results from a study in which participants encountered either (a) previously known informants who were positive (e.g. Abraham Lincoln), neutral (e.
