8500 Background: The role of adjuvant chemotherapy for pathological stage I non-small cell lung cancer (NSCLC) is controversial. The purpose of this study was to investigate the effect of adjuvant chemotherapy for pathological stage I NSCLC with high-risk factors for recurrence. Methods: Prospectively collected data from 1,278 patients with pathological stage I (8th edition) NSCLC undergoing lobectomy were retrospectively analyzed. High-risk factors for recurrence were determined by multivariable Cox proportional hazards model for recurrence-free survival (RFS). RFS, overall survival (OS), and cancer-specific survival (CSS) were compared between patients who received adjuvant chemotherapy and those who did not. Results: In multivariable analysis, age (≥70 y; hazard ratio [HR], 2.14), invasive component size ( > 2 cm; HR, 1.60), visceral pleural invasion (HR, 1.81), lymphatic permeation (HR, 1.67), and vascular invasion (HR, 2.78) were identified as independent factors for RFS. In patients with high-risk factors for recurrence such as invasive component size of > 2 cm, visceral pleural invasion, lymphatic permeation, or vascular invasion (high-risk group; n = 641), RFS was significantly different between patients who received adjuvant chemotherapy (n = 222; 5-y RFS, 81.4%) and those who did not (n = 418; 5-y RFS, 73.8%; P = 0.023). OS and CSS were also significantly better in patients who received adjuvant chemotherapy (5-y OS, 92.7%; 5-y CSS, 95.0%) than in those who did not (5-y OS, 81.7%; P < 0.0001; 5-y CSS, 89.5%; P = 0.012). In patients without any high-risk factors for recurrence (low-risk group; n = 637), RFS was not significantly different between patients who received adjuvant chemotherapy (n = 83; 5-y RFS, 98.1%) and those who did not (n = 554; 5-y RFS, 95.7%; P = 0.30). OS and CSS were also not significantly different between patients who received adjuvant chemotherapy (5-y OS, 98.0%; 5-y CSS, 100%) and those who did not (5-y OS, 95.6%; P = 0.35; 5-y CSS, 99.4%; P = 0.52). Conclusions: Adjuvant chemotherapy may improve survival in patients with pathological stage I NSCLC who have high-risk factors for recurrence such as invasive component size of > 2 cm, visceral pleural invasion, lymphatic permeation, or vascular invasion.

Stage Ii Colon Cancer

620 Background: For stage II colon cancer, the effect of postoperative adjuvant chemotherapy is still controversial. It is well known that tumor-associated macrophages (TAMs) play an important role in tumor progression. The aim of this study is to determine the effect of TAMs as predictor for adjuvant chemotherapy for stage II colon cancer. Methods: From July 2009 to June 2012, 521 patients with pathological stage II colon cancer were included. TAMs were detected using tissue microarray and immunohistochemistry (all TAMs detected by CD68; M2 subtype detected by CD206). The density of CD68+ TAMs, CD206+ TAMs and the ratio of CD206+ TAMs / CD68+ TAMs (CD206 / CD68 ratio) were calculated. The cut-off values were defined using X-Tile software. Results: High CD206+ TAMs density and high CD206 / CD68 ratio were significantly associated with reduced disease-free survival (DFS, P < 0.001 and P < 0.001, respectively) and overall survival (OS, P < 0.001 and P < 0.001, respectively). And CD206 / CD68 ratio had a better prognostic power. Furthermore, for patients with low CD206 / CD68 ratio, adjuvant chemotherapy made no benefit. But for high CD206 / CD68 ratio, adjuvant chemotherapy significantly improved DFS and OS (as shown in Table 1). In subgroup analysis, for T3 with high-risk factors or T4 tumors, CD206 / CD68 ratio was also a significant predictor for adjuvant chemotherapy (interaction P = 0.024 in DFS). Conclusions: For stage II colon cancer, CD206 / CD68 ratio was a good prognostic and predictive biomarker for adjuvant chemotherapy. Together with clinicopathological high-risk factors, it might facilitate patient counselling and individualise management. [Table: see text]

6039 Background: The predominant pattern of failure for Head and Neck Squamous Cell Carcinoma (HNSCC) is locoregional disease. Salvage surgery remains the standard of care for operable disease. Re-irradiation after previous full course radiotherapy generally has been considered contraindicated. Since anti-PD-1 antibodies were efficacious and safety in recurrent/metastatic HNSCC, this study aimed to evaluate the efficacy and safety of adjuvant toripalimab (anti-PD-1 antibody) in recurrent, previously irradiated HNSCC treated with salvage surgery. Methods: This study was a single-arm, phase II study. Patients with HNSCC occurring in an area of previously irradiated and with at least one high risk factors after salvage surgery (1- positive margin; 2- extranodal extension; 3- rStaging T3-4/N2-3/T2N1) were enrolled. In the Stage I of 12 patients, patients received toripalimab 240mg once every 3 weeks until confirmed disease progression or unacceptable toxicity, for 12 months. In the stage II of 8 patients with PD-L1 CPS≥1, patients received toripalimab combined with S-1, which was given orally at 25 mg/m2, twice daily, on day 1 to 14, repeated every 21 days for 4-6 cycles. The primary endpoint was 1-year progression-free survival (PFS). We hypothesized a 1-year PFS of at least 56% and assumed a null hypothesis of 34%. A retrospective cohort of 16 patients was compared. Results: Between May 2019 and December 2020, 20 patients were enrolled. High-risk factors included ENE (35%), positive margin (25%), T3-4(30%) and T2N+(10%). Seventeen patients have PD-L1 CPS≥1 and 3 patients have CPS＜1. With a median follow-up of 11.2 months, estimated 1-year PFS and overall survival was 57.0% (95% confidence interval, 32%– 77%) and 79.2% (51%–91%). The primary PFS endpoint has exceeded the hypothesis and its median has not been reached. When compared to the retrospective cohort, the PFS was significantly better(p=0.001)，even for Stage I patients(Median PFS: 5.1 vs 3.7 months, p=0.03 ). Stage II patients resulted a better PFS and OS compare to stage I (p=0.02 and p=0.002). For patients with CPS≥1, 1-year PFS and OS was 79.1% (95% confidence interval, 51%–91%) and 91.7%(68%–99%), which were significantly better than patients with CPS＜1 (p=0.001 and p=0.05). Adjuvant Toripalimab or combine with S-1 was well-tolerated with no grade 3-4 toxicity and dose interruption as a result of treatment-related adverse event only occurred in 2 patients. Flow cytometry revealed that patients with short PFS had fewer baseline overall count of B cells(p=0.09). Conclusions: Adjuvant Toripalimab or combined with S-1 after salvage surgery is efficacious and safety in recurrent, previously irradiated HNSCC, and a better PFS was observed in patients treated with combined therapy and with CPS≥1. Further randomized trials are warranted. Clinical trial information: NCT04126460.

To investigate the risk factors of complications in lung cancer patients after CT image-guided percutaneous lung biopsy (PTNB), in this study, 110 patients admitted to Xixi Hospital from January 30, 2017 to June 30, 2019 were selected for PTNB, and the basic characteristic information, lesion diameter, number of needle penetration, depth of needle penetration, physiological results of biopsy, postoperative concurrent symptoms, and success rate of biopsy were recorded. In addition, multivariate Logistic regression model (MLRM) was adopted to explore the correlation between various correlated characters and concurrent symptoms. The results showed that the biopsy pathological results were 53 cases of adenocarcinoma, 31 patients with squamous cell carcinoma, 8 patients with thymic carcinoma, 7 patients with small cell carcinoma and 11 patients with lymph carcinoma, and the success rate of needle biopsy was 100% by comparison with the final diagnosis. Among them, 35 patients developed pneumothorax symptoms postoperatively with a complication rate of 31.82%, 22 patients developed hemoptysis postoperatively with a complication rate of 20%, and 6 patients developed infection with a complication rate of 5.45%. The results of regression analysis showed that pneumothorax and hemoptysis were positively correlated with the number of de needles (P < 0.05), and negatively correlated with lesion diameter (P < 0.05). In addition, pneumothorax was also significantly positively correlated with age (P < 0.05), and infection was significantly positively correlated with the number of puncture needles (P < 0.05). Therefore, the main complications after PTNB are pneumothorax and hemoptysis, the high risk factors associated with pneumothorax include lesion diameter, number of puncture needles and age, the high risk factors associated with hemoptysis include lesion diameter and number of puncture needles, and the risk factors associated with infection are number of puncture needles.
