Unlabelled: Over the past decades, breast cancer (BC) is the most common cancer and one of the key causes of mortality and disability among women in developed countries.
Aim: Determination of the role of Ki-67 index in assessing the quality of neoadjuvant polychemotherapy treatment using regional or systemic delivery routes of pharmacological agents in patients with locally advanced breast cancer (LABC).
Materials And Methods: The retrospective analysis of 30 clinical trials of LABC treatment based on selective intra-arterial therapy in patients with BC (T4A-DN0-3M0) was used.
Results: The decrease in Ki-67 level in LABC after selective intra-arterial polychemotherapy was more pronounced than after systemic polychemotherapy. No correlation of the tumor metastatic potential with a Ki-67 level was detected.
Conclusion: Assessment of Ki-67 expression allows to evaluate effectively the biological properties of the tumor, predict the course of the disease and choose the optimal tactics of neoadjuvant polychemotherapy (regional or systemic variant) as part of integrated antitumor treatment.

Background: In recent years, the incidence of pancreatic cancer has shown an obvious increasing trend worldwide and even causes a greater disease burden to the mankind. Due to the lack of effective early surveillance methods, patients are often in the middle to advanced stages of their disease at the time of detection, thus losing the opportunity for surgery. The currently available chemotherapy regimens are yet to be further improved to prolong patient survival.

Background: Patients with human epidermal growth factor receptor 2 (HER2)-positive early breast cancer with residual invasive disease after neoadjuvant systemic therapy have a high risk of recurrence and death. The primary analysis of KATHERINE, a phase 3, open-label trial, showed that the risk of invasive breast cancer or death was 50% lower with adjuvant trastuzumab emtansine (T-DM1) than with trastuzumab alone.
Methods: We randomly assigned patients with HER2-positive early breast cancer with residual invasive disease in the breast or axilla after neoadjuvant systemic treatment with taxane-based chemotherapy and trastuzumab to receive T-DM1 or trastuzumab for 14 cycles.

The use of neoadjuvant chemotherapy (NAC) as a first-line therapy for advanced high-grade serous ovarian carcinoma (HGSOC) has increased. However, several studies have reported NAC-induced platinum resistance. This study aimed to evaluate the predictive impact of clinical factors on chemotherapy response score (CRS) and to select patients who would respond well to NAC.

Purpose: Pancreatic ductal adenocarcinoma (PDAC) is an aggressive malignancy with poor response to chemotherapy. High-frequency microsatellite instability (MSI-H) is a rare biological phenomenon in conventional PDAC, being more frequently described in tumors with medullary or mucinous features.
Methods And Results: In this manuscript, we report the case of a patient with an MSI-H pancreatic carcinoma with medullary features (medullary carcinoma of the pancreas-MCP) that achieved a complete pathological response after neoadjuvant modified FOLFIRINOX.

Purpose: Synchronous esophageal (EC) and rectal carcinoma (RC) is a rare and challenging condition, particularly in curative-intended treatment. Especially locally advanced tumors may not be suitable for primary resection and require individual multimodal treatment. This review examines curative-intended management of synchronous EC and RC.
