Since 1987 we have treated 17 patients with bone sarcomas of the extremities (14 osteosarcomas, 3 malignant fibrous histiocytomas), with 2 cycles of neoadjuvant chemotherapy, consisting in iv high dose Methotrexate, Cis-Platin in 3 days in continuous infusion, and iv Adriamycin every 29th day. We obtained "good necrosis" (greater than 90%) in 13 patients (76.5%). We briefly report the possible correlations between angiographic findings after the first cycle and response to chemotherapy. All patients but one (94%), underwent conservative surgery. To date no patients have had local recurrence; 12 patients (70.5%) are disease free at a median follow up of 21.5 months; in 5 patients lung metastases appeared. To define overall survival and disease-free survival a longer follow up is required.

Colorectal cancer (CRC) continues to be a significant global health issue contributing to a high mortality rate. Despite advancements in treatment, the risk of recurrence remains due to inherent mutations and the rapid turnover of intestinal mucosa. We present an exceptionally rare case of CRC metastasis to the duodenum in a 42-year-old female who has been compliant with postsurgical surveillance.

Background: Breast cancer (BC) is a common cancer among women worldwide, and although the use of neoadjuvant therapy (NAT) for BC has become more widespread, there is no standardized prediction of the efficacy of NAT for BC. This study aimed to evaluate the value of quantitative parameters of dual-layer detector spectral computed tomography (DLCT) in predicting whether BC patients can achieve pathological complete response (pCR) after NAT.
Methods: Patients who were first diagnosed with BC in Shandong Cancer Hospital and Institute and received only NAT before surgery were selected for participation in this study.

Department of Radiology, Qilu Hospital, Shandong University, Jinan, China.
Background: Hypoxia-inducible factor-1-alpha (HIF-1α) has the potential to predict the neoadjuvant chemotherapy (NAC) response in pancreatic ductal adenocarcinoma (PDAC). This study aimed to assess the relationship between the pathological response and intratumoral HIF-1α expression in patients with PDAC receiving NAC, and investigate the predictive value of contrast-enhanced computed tomography (CECT) features in HIF-1α expression.
Methods: A total of 58 patients from three centers with pathologically confirmed PDAC who underwent NAC followed by surgery were retrospectively enrolled in this study.

Objective: To evaluate the predictive value of pathological response and lymph node status on progression-free survival (PFS) in patients with potentially resectable non-small cell lung cancer (NSCLC) receiving neoadjuvant immunotherapy.
Methods: A retrospective analysis was conducted on 143 patients with potentially resectable NSCLC who underwent neoadjuvant immunotherapy followed by surgical resection. Pathological response, lymph node involvement, and clinical outcomes were comprehensively assessed using Kaplan-Meier analysis and Cox regression.

Background: The study aimed at assessing whether long-term survival outcomes were different based on tumor location in pancreatic ductal adenocarcinoma (PDAC) patients who underwent pancreatectomy following neoadjuvant chemoradiotherapy (CRT).
Methods: Following CRT, resection rate was 60.5% (286/473) and the resected patients had pancreatic head (n = 218), body (n = 34) and tail (n = 34) tumors.
