This study aimed to investigate the accuracy of three fixation methods in patients with left breast cancer receiving whole breast radiotherapy: conventional breast bracket (BB), breast bracket combined with deep inspiration breath holding (DIBH), and cervical-thoracic integrated bracket (CTIB) combined with DIBH.

To analyze the pattern of lymph node metastasis in esophageal cancer based on the theory of membrane anatomy.

Cancer is a severe threat to human health, and surgery is a major method of cancer treatment. This study aimed to develop an optical sensor for fast cancer tissue.

This study aimed to evaluate the impact of antibiotic exposure on efficacy and adverse reactions in non-small cell lung cancer (NSCLC) patients receiving chemoimmunotherapy, and to explore any specific associations on the basis of antibiotic class.

Hemolytic anemia is a rare and unique complication of alectinib, not observed with other anaplastic lymphoma kinase (ALK) inhibitors. Here, we present a case of an ALK fusion-positive non-small-cell lung cancer (NSCLC) patient who developed liver failure due to diffuse liver metastasis at initial diagnosis. Treatment was initiated with low-dose alectinib, but the patient developed severe hemolytic anemia. Switching to lorlatinib allowed for the continuation of ALK inhibitor therapy and successful tumor reduction. ALK inhibitors are crucial for ALK fusion-positive NSCLC patients. Managing severe side effects by switching medications is essential to maintain effective therapy. In this case, lorlatinib effectively controlled the tumor and improved the patient's liver function and performance status. This case highlights the importance of adapting treatment strategies to manage adverse effects while ensuring the continued use of ALK inhibitors for optimal patient outcomes.

Squamous cell carcinoma is the second most prevalent type of non-small cell lung cancer. Analyzing the molecular mechanisms underlying lung carcinoma requires useful tools, such as squamous lung cancer cell lines.

Protein tyrosine kinase 7 (PTK7) has been found to be highly expressed in non-small cell lung cancer (NSCLC), but its specific molecular mechanism needs to be further explored.

To search for a new biomarker that can predict the efficacy and prognosis of tumor immunotherapy.

This study aimed to compare long-term clinical outcomes of percutaneous needle biopsy (PCNB) versus surgical biopsy in patients with peripheral, small-sized clinical stage 1 non-small cell lung cancer (NSCLC) with computed tomography (CT)-defined visceral pleural invasion (VPI).

Metastasis to the thyroid gland from lung adenocarcinoma is rare and challenging to diagnose due to similar histopathological features. This study aimed to analyze the clinicopathological characteristics of and treatment strategies for lung adenocarcinoma metastasis to the thyroid based on 11 years of institutional experience.

Podoplanin (PDPN) expression in cancer-associated fibroblasts (CAFs) (CAF-PDPN) is considered a poor prognostic factor in nonsmall cell lung cancer, but little is known about its clinical significance in high-grade neuroendocrine carcinoma of the lung (HGNEC). This study examines the association between CAF-PDPN and stromal programmed death-ligand 1 (PD-L1) expression and the prognostic implications of CAF-PDPN and PD-L1 expression status in surgically resected HGNEC patients.

To conduct a comparative analysis of clinicopathological data between mucinous micropapillary breast carcinoma (MUMPC) and pure mucinous carcinoma (PMC) without a micropapillary structure to elucidate the distinctive clinicopathological characteristics of MUMPC and their impact on prognosis.

To evaluate the impact of antibiotic (ATB) exposure on the outcome of chemoimmunotherapy in patients with extensive-stage small cell lung cancer (ES-SCLC).

Hippo-avoidance prophylactic cranial irradiation (HA-PCI) requires a hippocampal avoidance zone expanded from hippocampus to ensure dose fall-off and compensate for setup errors. Most studies recommend a 5-mm margin, while it could be optimized to a 2-mm expansion. Here, we showed the details of optimized HA-PCI for limited-stage small cell lung cancer (LS-SCLC).

Arising from the urachal epithelial lining, the urachal carcinoma is a rare tumor, which accounts for 0.35%-0.7% of all bladder cancers. Urachal carcinoma has a higher predilection in men with median age around 50-60 years old. The most common clinical symptom is intermittent painless gross hematuria, and less-reported presentations include suprapubic mass, dysuria, lower abdominal pain, and frequent urination. The pathological study reveals that most cases (90%) are categorized as an intestinal adenocarcinoma subtype, while other morphological variants, including mucinous, enteric, signet ring cell subtype, not otherwise specified (NOS), squamous cell carcinoma, urothelial carcinoma, sarcoma, small cell carcinoma, and undifferentiated carcinoma, totally account for about 10%. The urachal carcinoma occurs mostly in the lower segment of urachal tube and bladder dome or anterior wall. However, due to the classically silent nature of the early lesions and high malignancy, urachal carcinoma patients are commonly diagnosed in advanced stage. Treatment modalities for local recurrence or metastatic urachal cancer include surgery and chemotherapy (cisplatin and 5-FU based-chemotherapy). Meanwhile, the EGFR-, PD-L1-, and MEK-targeted therapies in the metastatic urachal carcinoma cases showed satisfactory response. We presented a rare case of Sheldon stage IVB urachal adenocarcinoma with pulmonary metastasis, and the patient had no progression of disease 6 months following surgical treament without chemoradiotherapy.

This study aimed to analyze the role of circSEC24A in non-small cell lung cancer (NSCLC) and its underlying mechanism.

Pemetrexed is a key therapeutic agent for advanced non-squamous non-small cell lung cancer (Nsq-NSCLC), yet it is associated with renal toxicity. This study aims to elucidate the incidence, risk factors, and survival impact of renal injury in patients with Nsq-NSCLC treated with pemetrexed.

Increasing evidence shows that exosome-mediated delivery of circular RNA (circRNA) is implicated in breast cancer progression. This study aimed to elucidate the role of exosome-transported circ_0001955 in breast cancer.

A 73-year-old woman was admitted to our hospital with severe respiratory distress due to postpneumonectomy neoplastic central airway obstruction. An emergency recanalization with rigid bronchoscopy (RB) was planned. Controlled and jet ventilation are routinely used to assure ventilation during RB, but the risk of inadequate oxygenation and removal of carbon dioxide was prohibitively high in this case due to the presence of a single lung. The use of venovenous extracorporeal membrane oxygenation was decided by multidisciplinary team to support ventilation during RB. Complete airway recanalization was successfully achieved without any complications. The patient was discharged 2 days later. Pathology revealed metastatic adenocarcinoma, and the patient was reviewed for oncologic treatment.

With the rising incidence of pulmonary nodules (PNs), lung adenocarcinoma in situ (AIS) is a critical early stage of lung cancer, necessitating accurate diagnosis for early intervention. This study applies artificial intelligence (AI) for quantitative imaging analysis to differentiate AIS from atypical adenomatous hyperplasia (AAH) and minimally invasive adenocarcinoma (MIA), aiming to enhance clinical diagnosis and prevent misdiagnosis.
