Efficacy and safety of neoadjuvant immunotherapy plus chemotherapy followed by adjuvant immunotherapy in resectable non-small cell lung cancer: a meta-analysis of phase 3 clinical trials.

Objective: At present, several important trials have been published show that perioperative immunotherapy combined with chemotherapy can improve the prognosis of patients with resectable non-small cell lung cancer, which further optimizes treatment options. Therefore, we conducted a systematic review and meta-analysis to evaluate the efficacy and safety of perioperative immunotherapy combined with chemotherapy in resectable non-small cell lung cancer. Methods: The following databases were searched for relevant studies: PubMed, EMBASE, Cochrane library (updated 12 October 2023). All randomized trials comparing perioperative immunotherapy combined with chemotherapy versus chemotherapy alone in resectable non-small cell lung cancer were eligible for inclusion. Data were analyzed using Review Manager 5.4.1 (Cochrane collaboration software). Primary outcomes and measures included overall survival (OS), event-free survival (EFS), pathological complete response (pCR), major pathological response (MPR), R0 resection rate, rate of underwent surgery and adverse events (AEs). Results: A total of 2912 patients (1453 receiving perioperative immunotherapy plus chemotherapy and 1459 receiving chemotherapy alone) were included in this systematic review and meta-analysis. The result showed that compared with chemotherapy alone, combined therapy significantly improved OS (HR = 0.68;95% CI: 0.56-0.83), EFS (HR = 0.58;95% CI: 0.51-0.65), pCR (OR = 7.53;95% CI: 4.63-12.26), MPR (OR = 5.03;95% CI: 3.40-7.44), R0 resection (OR = 1.58;95% CI: 1.152.18) and rate of underwent surgery (OR = 1.25;95% CI: 1.04-1.49). However, combination therapy was associated with higher risk of severe adverse event (OR = 1.46;95% CI: 1.19-1.78; P=0.0002), grade 3 and higher treatment-related adverse event (TRAE) (OR = 1.25;95% CI: 1.06-1.49; P=0.010), TRAE that led to interruption (OR = 1.90;95% CI: 1.34-2.68; P=0.0003) and immune-related adverse event (OR = 2.78;95% CI: 2.18-3.55; P<0.00001). Significant benefits were observed across most subgroups of EFS and pCR. However, no statistical differences were observed for EFS of never smoked (HR = 0.73;95% CI: 0.51-1.05) and EGFR-mutation positive (HR = 0.35;95% CI: 0.04-3.03). Conclusion: This systematic review and meta-analysis found superior efficacy associated with perioperative immunotherapy plus chemotherapy compared with chemotherapy alone in both tumor regression and prolonged survival in resectable NSCLC, but increased the risk of TRAE, so monitoring for adverse events is warranted.

Efficacy of tyrosine kinase inhibitors in patients with advanced or metastatic sarcomas after prior chemotherapy: A meta-analysis.

BACKGROUND: Sarcoma is a heterogeneous malignancy arising from interstitial tissue. Anthracycline-based therapy is the first-line treatment recommended by guidelines for patients with locally advanced or metastatic unresectable sarcoma. Recently, targeted therapies, in particular tyrosine kinase inhibitors (TKIs), have made significant progress in the treatment of sarcoma, and their efficacy has been investigated in randomized controlled trials. The aim of this meta-analysis is to evaluate the efficacy of TKIs in patients with advanced or metastatic sarcoma who have previously received chemotherapy. METHODS: We completed a meta-analysis after conducting literature searches in PubMed, Embase, and Cochrane. The single-drug, placebo-controlled, randomized controlled clinical trials of TKIs in patients with advanced or progressive sarcoma who have previously received chemotherapy are available for inclusion in the study. The observation results were objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), and overall survival (OS). The subgroup analysis was performed according to histological subtypes of sarcoma. RESULTS: This study included 6 studies, including 1033 patients. The ORR (OR: 7.99, 95% CI: 3.62-19.61, P < .00001), DCR (OR: 2.54, 95% CI: 1.27-5.08, P = .009), PFS (HR: 0.46, 95% CI: 0.34-0.62, P < .00001), and OS (HR: 0.80, 95% CI: 0.67-0.96, P = .02) of patients treated with TKIs were better than those in the placebo group. CONCLUSIONS: In patients with advanced sarcoma, TKIs have been shown to have advantages in terms of ORR, DCR and PFS and OS. Multi-targeted TKIs may be considered as one of the second-line treatment options for sarcoma patients who have received prior chemotherapy.

Efficacy and safety of neoadjuvant chemoradiotherapy versus neoadjuvant chemotherapy in locally advanced esophageal cancer: An updated meta-analysis.

BACKGROUND: Currently, the optimal treatment for neoadjuvant therapy for locally advanced esophageal cancer is not clear, and there is no evidence that neoadjuvant chemoradiotherapy (nCRT) is superior to neoadjuvant chemotherapy (nCT). Due to the publication of new clinical trials and defects in previous meta-analyses, we conducted an updated meta-analysis to evaluate the efficacy and safety of nCRT and nCT. METHODS: The following databases were searched for studies: PubMed, EMBASE, and Cochrane library (updated to April 22, 2023). All randomized trials comparing nCRT with nCT in locally advanced esophageal cancer met the inclusion criteria. Data were analyzed using Review Manager 5.4.1 (Cochrane collaboration software). Primary outcomes assessed from the trials included overall survival (OS), progression-free survival (PFS), pathological complete response (pCR), R0 resection rate, postoperative complications, postoperative mortality, and grade 3 or higher adverse events (3 + AEs). RESULTS: This systematic review and meta-analysis included 7 randomized controlled studies involving 1372 patients (686 receiving nCRT and 686 receiving nCT). Compared with nCT, nCRT significantly improved OS (HR = 0.80; 95% CI: 0.68-0.94), PFS (HR = 0.78; 95% CI: 0.66-0.93), pCR (OR = 13.00; 95% CI: 7.82-21.61) and R0 resection (OR = 1.84; 95% CI: 1.32-2.57), but was associated with higher postoperative mortality (OR = 2.31; 95% CI: 1.26-4.25) and grade 3 + AEs (OR = 2.21; 95% CI: 1.36-3.58). There was no significant difference in postoperative complications between nCRT and nCT (OR = 1.15; 95% CI: 0.82-1.61). Subgroup analysis showed significant survival benefit in squamous cell carcinoma (HR = 0.80; 95% CI: 0.68-0.98), but not in adenocarcinoma (HR = 0.80; 95% CI: 0.63-1.08). CONCLUSIONS: Our meta-analysis found superior efficacy associated with nCRT compared with nCT in both tumor regression and prolonged survival, but increased the risk of postoperative mortality and grade 3 + AEs. Esophageal squamous cell carcinoma was more likely to benefit from nCRT than esophageal adenocarcinoma in the term of OS.

Rectal metastasis of gastric cancer: a case report.

The most common metastatic sites of gastric cancer include the liver, peritoneum, lung, and bone. However, there is a lack of relevant clinical reports regarding rectal metastasis. Herein, we report the rare case of a patient with gastric cancer who developed rectal metastasis. A 57-year-old male patient was diagnosed with gastric cancer and underwent a radical gastrectomy in January 2016, followed by eight cycles of adjuvant chemotherapy. The patient subsequently developed a rectal mass in March 2021. He was diagnosed with rectal adenocarcinoma and underwent surgical resection of the rectal tumor. A mass was then found in the abdominal wall in September 2021 and was resected. Specimens obtained from the three surgeries were reviewed, and the rectal tumor and the mass in the abdominal wall were both found to be metastatic tumors from the gastric cancer. Metastasis of gastric cancer to the rectum is rare, but it is important to differentiate between rectal metastasis and primary rectal cancer to help avoid unnecessary treatment.

Efficacy and safety of zolbetuximab for first-line treatment of advanced Claudin 18. 2-positive gastric or gastro-esophageal junction adenocarcinoma: a systematic review and meta-analysis of randomized controlled trials.

Objective: Zolbetuximab is a "first-in-class" chimeric lgG1 monoclonal antibody targeting Claudin18.2 (CLDN 18.2). In recent years, several important trials have been published showing that zolbetuximab is associated with improved prognosis in patients with advanced gastric or gastro-esophageal junction (G/GEJ) adenocarcinoma. This promises great change to the current treatment landscape. Therefore, we conducted a systematic review and meta-analysis to evaluate the efficacy and safety of zolbetuximab for first-line treatment of advanced CLDN 18. 2-positive G/GEJ adenocarcinoma. Methods: The following databases were searched for relevant studies: PubMed, EMBASE, and Cochrane library (updated 10 June 2023). All randomized trials comparing zolbetuximab plus chemotherapy versus first-line chemotherapy alone for first-line treatment of advanced CLDN 18. 2-positive G/GEJ adenocarcinoma were eligible for inclusion. Data were analyzed using Review Manager 5.4.1 (Cochrane collaboration software). Primary outcomes and measures included overall survival (OS), progression-free survival (PFS), objective response rate (ORR), and adverse events (AEs). Results: This systematic review and meta-analysis included three randomized controlled studies involving 1,402 patients (699 receiving zolbetuximab plus chemotherapy and 703 receiving chemotherapy alone). Compared with chemotherapy alone, zolbetuximab plus chemotherapy significantly improved OS (HR = 0.73; 95% CI: 0.68-0.84) and PFS (HR = 0.64; 95% CI: 0.50-0.82), but did not result in a higher ORR (RR = 0.92; 95% CI: 0.82-1.03). Further analysis of CLDN 18.2 expression showed a more significant benefit for OS (HR = 0.69; 95% CI: 0.55-0.87; p = 0.002) and PFS (HR = 0.61; 95% CI: 0.44-0.84; p = 0.003) from zolbetuximab in patients with high expression, while there was significant benefit in patients with lower expression. In terms of AEs, zolbetuximab plus chemotherapy was associated with higher risk of grade 3 and higher AEs, but increased risk of nausea and vomiting were more common. Conclusion: This systematic review and meta-analysis revealed that the effect of zolbetuximab plus chemotherapy was superior to that of chemotherapy alone for first-line treatment of advanced CLDN 18.2-positive G/GEJ adenocarcinoma. Thus, zolbetuximab plus chemotherapy represents a new first-line treatment for these patients. Zolbetuximab plus chemotherapy was associated with higher risk of grade 3 and higher AEs, but was generally manageable.

Pseudoprogression Disease in a Patient with Small Cell Lung Cancer on Immune Checkpoint Inhibitor Therapy.

Small cell lung cancer (SCLC) accounts for approximately 15% of all lung cancers and is on the rise annually. It is characterized by low differentiation, high malignancy, and rapid growth. Consequently, treatment options are limited, and the patient's prognosis is poor. The emergence of immunotherapy has partially improved the survival and prognosis of SCLC patients. However, a unique response known as "pseudoprogression" during immunotherapy has raised concerns. The occurrence of tumor enlargement despite a positive response to immune checkpoint inhibitor therapy undoubtedly affects the assessment of clinical drug efficacy and the selection of subsequent treatment strategies. In this article, we analyze a clinical case of pseudoprogression in a patient with SCLC who received immune therapy (Durvalumab). Currently, there is insufficient evidence-based medicine to guide the diagnosis, differentiation and subsequent treatment strategies for pseudoprogression in SCLC following immunotherapy. Through this case report and literature review, we aim to provide diagnostic and therapeutic insights for the clinical use of immunotherapy in advanced SCLC. Additionally, we hope that fellow readers of this article can engage in further collaborative discussions through more clinical research.

Ascending colon cecal junction carcinoma with prostate metastasis: A case report and literature review.

RATIONALE: Colon carcinoma is the most common type of cancer, and a leading cause of cancer-related death. Clinically, the most common sites of metastases from colon carcinoma are the liver, lungs, peritoneum, and lymph nodes, while the incidence of metastases to the prostate is low. There are few relevant studies on colon carcinoma, most of them being case reports. PATIENT CONCERNS: A 76-year-old man treated with radical resection of right colon carcinoma due to primary poorly differentiated adenocarcinoma of the cecum. Postoperative pathological examination suggested that he had cancer at the junction of the ascending colon and the cecum. He had received adjuvant chemotherapy after surgery. One year later, he received transurethral plasma resection of the prostate due to urinary system discomfort. Postoperative pathological immunohistochemistry suggested prostate metastasis of colorectal carcinoma, and he received individualized treatment, but this produced no clear survival benefit. DIAGNOSES: Ascending colon cecal junction carcinoma with prostate metastasis. INTERVENTIONS: Radical resection, chemotherapy, anti-androgen therapy, surgery to relieve primary lesion obstruction symptoms, and local radiotherapy of the prostate. OUTCOMES: At present, clinical cases of colon carcinoma with prostate metastasis are rare. By sharing a rare case of ascending colon cecal junction carcinoma with prostate metastasis and reviewing the relevant literature, this paper explores and optimizes the clinical treatment of colon carcinoma with prostate metastasis.

Colorectal cancer with testicular metastasis: A case report and literature review.

RATIONALE: Colorectal cancer is the second leading cause of cancer-related deaths in the world. About 50% of patients will have metastases during the course of the disease. The common sites of metastasis are the liver, lung, peritoneum, lymph, etc. Metastatic carcinoma to the testes is uncommon. We found a case of ascending colon cancer metastasized to the testis in the clinic. PATIENT CONCERNS: We reported a 50-year-old male patient who was found to have testicular metastases >4 years after intestinal cancer surgery, and multiple metastases in the peritoneum and pelvis were found 1 week later. DIAGNOSES: After enhanced computed tomography and pathological biopsy, the patient was diagnosed with testicular metastasis of colon cancer. INTERVENTIONS: Capecitabine combined with bevacizumab is currently undergoing palliative treatment. OUTCOMES: The patients died of tumor progression on June 28, 2021. LESSONS: The testicular metastasis of colorectal cancer is a sign of peritoneum and multiple metastases. When the testicular metastasis occurs in colorectal cancer patients, it usually indicates that the patient has a poor prognosis.

Major pathological remissions in a patient with stage IIIA nonsmall cell lung cancer after neoadjuvant tislelizumab combined with chemotherapy: a case report and literature review.

INTRODUCTION: Currently, there are few reports of patients with locally advanced lung cancer achieving a clinical complete response by medical treatment. Preoperative neoadjuvant immunotherapy combined with chemotherapy is an option for patients with unresectable, locally advanced nonsmall cell lung cancer (NSCLC) which is of great potential, and may change traditional treatment paradigms. There are relatively few large-scale, high-quality randomized-controlled trials yet, and limitations such as short postoperative follow-up period and immature disease-free survival and overall survival data still persist. Thus, evidence-based medical evidence is urgently needed. It is worthy to explore the further treatment of patients who achieved complete response after initial treatment, though lacking of evidence by now. CASE PRESENTATION: We report a stage IIIA lung squamous cell carcinoma case who achieved a major pathologic remission after neoadjuvant treatment with tislelizumab and chemotherapy. CONCLUSION: Our case study contributes to the existing evidence on the feasibility, efficacy and safety of neoadjuvant immunotherapy combined with chemotherapy in locally advanced unresectable NSCLC.

A single-center randomized controlled study of intraperitoneal hyperthermic chemoperfusion in combination of recombinant human tumor necrosis factor (TNF) in treatment of malignant ascites caused by advanced abdominal cancers.

INTRODUCTION: Malignant peritoneal effusion is a common complication of advanced malignancies, which has a poor prognosis for patients. Hyperthermic intraperitoneal chemotherapy (HIPEC) has been widely used in the treatment of advanced gynecological tumors, especially ovarian cancer (OC). Relative studies have indicated that HIPEC allows for direct exposure of tumor cells to high peritoneal concentrations of cytotoxic drugs without increasing systemic toxicity compared with intravenous treatment. Recombinant human tumor necrosis factor for injection (rmhTNF-NC) is a safely tolerated immunotherapeutic drug that has becoming a mainstay of treatment for malignant effusions. Currently, a prospective study is required to determining the efficacy of rmhTNF-NC plus cisplatin for the treatment of malignant peritoneal effusion for OC. METHODS: Design and setting: This is a single-center, open trial will be performed in Zhongshan Affiliated Hospital, Guangzhou University of Chinese Medicine. PARTICIPANTS: Eligible patients will be those with advanced gynecologic cancers and who would be suitable for HIPEC. INTERVENTION AND CONTROL: HIPEC with cisplatin and intraperitoneal perfusion with rmhTNF-NC. COINTERVENTIONS: Further chemotherapy will be offered to patients as per current practice.OutcomesPilot study: Patients and clinicians' acceptability of the trial to assist in optimization of recruitment.Primary outcome: One-year overall survival (OS).Secondary outcomes: Progression-free survival (PFS), adverse events.Follow-up: One-year follow-up for OS.Sample size: Twenty patients to demonstrate therapeutic effect of peritoneal effusion caused by OC. DISCUSSION: This trial will determine the effectiveness of HIPEC with cisplatin and intraperitoneal perfusion with rmhTNF-NC for advanced gynecologic cancers, and guide the optimal treatment for these patients.

Isolated adrenocorticotropic hormone deficiency associated with sintilimab therapy in a patient with advanced lung adenocarcinoma: a case report and literature review.

BACKGROUND: Several immune checkpoint inhibitors have been implemented for cancer treatment which have shown some degree of antitumor effcacy, while immune-related adverse events (irAEs) that affect multiple organ functions ensue which obviously should not be neglected. Though less common than other kinds of irAEs, Immune checkpoint inhibitors (ICIs) related Isolated ACTH deficiency (IAD) may cause long-term damage to pituitary-adrenal axis. Several case reports are available about IAD during anti-PD-1 therapy. We report the first case of immune checkpoint inhibitor-induced IAD following 3 month of sintilimab therapy. CASE PRESENTATION: A 66-year-old Chinese man was diagnosed with stage IIIB lung adenocarcinoma with involving ipsilateral intrapulmonary and hilar lymph node metastasis. After 3 months of combination therapy of nedaplatin, pemetrexed and sintilimab, the patient presented with general fatigue, nausea and vomiting. Laboratory investigation at admission revealed hyponatremia and hypokalemia. Further investigation revealed adrenocorticotropic hormone and cortisol levels were far below than normal limits. His other pituitary hormone levels were normal, except for mild elevation of follicle stimulating hormone and estradiol. Cranic magnetic resonance imaging showed a normal pituitary gland. Isolated adrenocorticotropic hormone deficiency was diagnosed, and corticosteroid replacement therapy was administered, leading to a significant improvement of his symptoms while ACTH level maintaining low level. CONCLUSIONS: Our patient developed isolated ACTH deficiency during combination cancer treatment with chemotherapy and sintilimab. Although isolated ACTH deficiency due to anti-PD-1 including sintilimab therapy is rare occurrence, it can often cause severe clinical symptoms. Its diagnosis basically relies on clinical symptoms and endocrinological examination. Unlike traditional hypophysitis diagnosed by cranial MRI, pituitary MRI of IAD due to anti-PD-1 often indicates normal pituitary gland implying that over-reliance on imaging findings is not recommended. Even if clinical symptoms have relieved after corticosteroid replacement therapy was commenced, low levels of ACTH or cortisol could maintain for a long period which highlights the need for long term corticosteroid therapy. The purpose of the current report was to provide increased awareness of early detection and therapy of IAD.

Case report: pathological complete response in an IIIB non-small cell lung cancer patient after preoperative neoadjuvant nivolumab therapy combined with chemotherapy.

RATIONALE: For locally advanced non-small cell lung cancer (NSCLC), the neoadjuvant therapy strategy of preoperative nivolumab combined with chemotherapy has great potential, especially for locally advanced NSCLC which are initially unresectable. They may be cured after neoadjuvant immunotherapy, and this may become a new direction of treatment. We hope that this representative medical record and literature review can provide some assistance for clinicians using immune checkpoint inhibitors to treat lung cancer. PATIENT CONCERNS: A 50-year-old male patient was admitted to Zhongshan Hospital of Traditional Chinese Medicine on April 27, 2020 due to "coughing for more than one month.". The patient had nothing of note in either his medical history or that of his family, and no history of smoking. DIAGNOSIS: The diagnosis was cT4N2M0IIIB stage right lower lung NSCLC with right hilar and mediastinal lymph node metastasis. The stage was inoperable stage IIIB NSCLC, but the patient had a strong willingness for doing surgery. INTERVENTIONS: The patient received 3 rounds of the neoadjuvant nivolumab therapy combined with TP (paclitaxel plus cisplatin) regimen, on 5-14-21, 06-07-21 and 07-07-21. OUTCOMES: The tumor's area shrunk. Then the patient underwent thoracoscopic radical resection of the cancer in the right upper lung and postoperative pathology achieved pathological complete response (pCR). LESSONS: In this case, combined with the wishes of the patient and the latest research results, we confirmed pCR by radical surgery after 3 rounds of the neoadjuvant nivolumab therapy combined with chemotherapy. This may be a modality to cure more lung cancer patients in the future.

Efficacy and safety of salvage radiotherapy combined with endocrine therapy in patients with biochemical recurrence after radical prostatectomy: A systematic review and meta-analysis of randomized controlled trials.

Background: The addition of endocrine therapy to salvage radiotherapy (SRT) is expected to further improve the prognosis of patients with biochemical recurrence of prostate cancer after radical prostatectomy (RP). The quantitative synthesis of clinical outcomes of SRT combined with endocrine therapy is limited. Whether salvage radiotherapy plus endocrine therapy remains inconclusive. We performed a systematic review and meta-analysis of existing randomized controlled trials to evaluate the efficacy and safety of salvage radiotherapy combined with endocrine therapy in patients with biochemical recurrence after radical prostatectomy. Methods: A systematic search of PubMed, EMBASE, and the Cochrane library was performed for articles published between January 1, 2012 and October 10, 2022. Data were analyzed using Review Manager 5.4.1 (Cochrane Collaboration Software). Main outcome and measures included biochemical progression-free survival (bPFS), metastasis free survival (MFS), overall survival (OS), and Grade 3 or higher adverse events (3+AEs), including acute and late adverse events. Results: In this systematic review and meta-analysis, 4 randomized controlled studies enrolling 2731 male (1374 of whom received SRT combined with endocrine therapy and 1357 controls) met the inclusion criteria. SRT combined with endocrine therapy were related to significantly improve bPFS (HR=0.52; 95% CI: 0.46 0.59; p<0.00001) and MFS (HR=0.75; 95% CI: 0.64 0.88; p<0.001). Compared with SRT alone, the combination therapy tended to be associated with prolong OS (HR=0.83; 95% CI: 0.69-1.01; p=0.06), but not statistically significant. At early follow-up, the risk of acute AEs was comparable in the two groups (RR=1.04; 95% CI: 0.22-4.85). However, the risk of late AEs was higher in the combination group at later follow-up (RR=1.33; 95% CI: 1.09-1.62). Conclusions: This systematic review and meta-analysis found superior efficacy associated with adding endocrine therapy to SRT compared with SRT alone in patients with biochemical recurrence after RP. Additional endocrine therapy is safe and feasible for patients with biochemical recurrence after RP. Systematic review registration: https://www.crd.york.ac.uk/prospero, identifier (CRD42022365432).

Ablation Therapy Combined with EGFR TKIs in the Treatment of Advanced Non-Small Cell Lung Cancer: A Meta-Analysis of Randomized Controlled Trials.

OBJECTIVE: Systematically evaluate the efficacy of physical ablation combined with TKI in the treatment of advanced non-small cell lung cancer (NSCLC). METHODS: We performed a comprehensive search of databases including OVID, PubMed, EMBASE, the Cochrane Library, and three Chinese databases (China National Knowledge Infrastructure, Wanfang Database, and Chongqing Weipu Database). The aim was to identify randomized controlled trials (RCT) investigating physical ablation as the treatment for advanced NSCLC. We also evaluated the methodological quality of the included studies and summarized the data extracted for meta-analysis with Review Manager 5.3. RESULTS: A total of 9 studies, including 752 patients, were evaluable. The meta-analysis results show that the complete response rate (CRR) (RR: 2.23, 95% CI: 1. 46 to 3.40, P 0.01), partial response rate (PRR) (RR: -2.25, 95% CI: 1.41 to 3.59, P 0.01), and disease control rate (DCR) (RR: -2.80, 95% CI: 1.64 to 4.80, P< 0.01) of patients with advanced NSCLC who received physical ablation combined with TKI therapy were higher than those who did not receive physical ablation therapy. The control groups from seven of the studies had a total of 606 patients with targeted therapies and chemotherapy. The complete response rate was (CRR) (RR: 2.48, 2.4895% CI: 1.55 to 2.47, P 0.01), partial response rate (PRR) (RR: -1.66, 95% CI: 1.20 to 2.31, P< 0.01), and disease control rate (DCR) (RR: -2.68, 95% CI: 1.41 to 5.06, P< 0.01) for patients with advanced NSCLC who had received physical ablation combined with targeted therapies and chemotherapy, compared to patients who had not received physical ablation therapy. This difference was statistically significant. Above all, these results showed that the clinical efficacy of physical ablation combined EGFR-TKIs therapy (regardless of whether it was combined with chemotherapy) was better than that of EGFR-TKIs therapy alone. CONCLUSION: Physical ablation combined with TKI treatment in patients with advanced NSCLC can improve efficacy.

Effective Treatment of NSCLC with Surgery After Nivolumab Combined with Chemotherapy: A Case Report and Brief Review of the Literature.

INTRODUCTION: Immuno checkpoint inhibitors (ICIs) including anti-PD-L1 antibody have shown certain therapeutic effects on various cancer types. Here, we reported a case of the patient with resectable non-small cell lung cancer (NSCLC) showing a complete response to nivolumab combined with chemotherapy. PATIENT INFORMATION: A 66-year-old male was diagnosed with stage IIIA large cell lung cancer, cT2N2M0, who was considered impossible to have a tumor resection due to his right hilar node enlargement. The diameter of the neoplasms was 22mm, and the patient wanted to get the chance of surgery. Light of all, surgery was the only radical treatment option and therefore planned. INTERVENTIONS: After administering 2 cycles of nivolumab combined with paclitaxel and cisplatin, the second chest computed tomography (CT) after the first scanning revealed the tumor apparent shrinking and vascular compression was disappeared than before. We performed a right upper lobectomy and mediastinal lymph node dissection. Pathologically, we confirmed no large cell lung cancer cells in the resected lung specimen. OUTCOMES: The follow-up showing that patient remains alive without recurrence to these days. CONCLUSION: This case report may provide a clue to the future development of induction therapy using nivolumab and surgery. The combined treatment of nivolumab and chemotherapy is likely to be considered as an optional management of resectable NSCLC.

Traditional Chinese Medicine Preparation Combined Therapy May Improve Chemotherapy Efficacy: A Systematic Review and Meta-Analysis.

BACKGROUND: Whether traditional Chinese medicine preparation combined therapy can improve the efficacy of chemotherapy is controversial. This meta-analysis evaluates the efficacy of traditional Chinese medicine preparation combined with chemotherapy. METHOD: Three databases were searched from inception through August 2018. Eligible randomized controlled trials (RCTs) involving the combined treatment of chemotherapy and traditional Chinese medicine preparation compared to chemotherapy alone for treating cancer were retrieved. The methodological quality of the included RCTs was assessed with Cochrane Collaboration's risk of bias assessment tool. Meta-analysis was adopted to make comprehensive comparisons between the experimental and control groups. RESULTS: Four RCTs were included in this review, comprising 256 subjects. The majority of the RCTs were judged as being of poor methodological quality. Meta-analysis showed that the combination of traditional Chinese medicine preparation and chemotherapy appeared to be more effective than chemotherapy alone, for the treatment of cancer, as assessed by the disease control rate (RR: 1.41, 95% CI: 1.11 to 1.79) and the objective response rate (RR: 2.71, 95% CI: 1.28 to 5.77). There were no statistically significant differences between the groups in terms of bone marrow suppression (RR: 0.88, 95% CI: 0.57 to 1.37) or gastrointestinal reaction (RR: 1.12, 95% CI 0.75 to 1.69). CONCLUSIONS: Traditional Chinese medicine preparation combined with chemotherapy may improve objective response rates and disease control rates more than chemotherapy alone. The evidence that combined traditional Chinese medicine preparation can reduce the side effects of chemotherapy is insufficient. More rigorous randomized controlled trials are needed to confirm these conclusions.
