RESUMEN
BACKGROUND: Prognosis of patients who achieve pathological complete response (pCR) with neoadjuvant therapy (NAT) is better than that of non-pCR patients. Currently, there is no indication for adjuvant immune checkpoint inhibitor therapy after achieving pCR. However, recurrence risk after pCR is reportedly 10%-20% with a poor prognosis. Therefore, we investigated the preoperative risk factors for recurrence in patients with pCR. METHODS: We analyzed 56 patients with esophageal squamous cell carcinoma who underwent esophagectomy after neoadjuvant chemoradiotherapy (NACRT) or neoadjuvant chemotherapy (NAC) and were histologically diagnosed with pCR. Preoperative factors were compared between patients with and without recurrence to identify the risk factors. RESULTS: Forty-eight patients who achieved pCR received NACRT and 8 received NAC. Ten patients who experienced recurrence (17.9%) had undergone NACRT. The cN2 lesions were more frequent, and pre-NAT blood hemoglobin (Hb) was lower in the recurrence group. In addition, the pre-NAT cross-sectional area (CSA) product of the major and minor diameters of the primary tumor before NAT was significantly higher in recurrent cases (p = 0.041). Multivariate analysis, including the cTNM stage, pre-NAT Hb, and pre-NAT CSA, identified high pre-NAT CSA as the only risk factor for recurrence (odds ratio 11.6, 95% confidence interval 1.3-104.1, and p = 0.028). Cox regression analysis of recurrence-free and overall survival identified only high pre-NAT CSA as a prognostic factor. CONCLUSIONS: The recurrence risk is relatively high even in patients who achieve pCR after NAT. High pre-NAT CSA of the primary tumor is a risk factor for recurrence necessitating close surveillance.

BACKGROUND: There are few reports on the associations between lymph node (LN) status, determined by preoperative 18F-fluorodeoxyglucose-positron emission tomography (FDG-PET), and prognosis in patients with locally advanced esophageal squamous cell carcinoma (ESCC) who underwent esophagectomy post-neoadjuvant chemotherapy (NCT). Additionally, details on the diagnostic performance of LN metastasis determination based on pathological examination versus FDG-PET have not been reported. In this study, we aimed to evaluate the associations among LN status using FDG-PET, LN status based on pathological examination, and prognosis in patients with locally advanced ESCC who underwent esophagectomy post-NCT. METHODS: We reviewed the data of 124 consecutive patients with ESCC who underwent esophagectomy with R0 resection post-NCT between December 2008 and August 2022 and were evaluated pre- and post-NCT using FDG-PET. The associations among LN status using FDG-PET, LN status based on pathological examination, and prognosis were assessed. RESULTS: Station-by-station analysis of PET-positive LNs pre- and post-NCT correlated significantly with pathological LN metastases (sensitivity, specificity, and accuracy pre- and post-NCT: 51.6%, 96.0%, and 92.1%; and 28.2%, 99.5%, and 93.1%, respectively; both p < 0.0001). Using univariate and multivariate analyses, LN status determined using PET post-NCT was a significant independent predictor of both recurrence-free survival and overall survival. CONCLUSION: The LN status assessed using FDG-PET post-NCT was significantly associated with the pathological LN status and prognosis in patients with ESCC who underwent esophagectomy post-NCT. Therefore, FDG-PET is a useful diagnostic tool for preoperatively predicting pathological LN metastasis and survival in these patients and could provide valuable information for selecting individualized treatment strategies.

BACKGROUND: Pathological lymph node metastasis (LNM) following multimodal therapy is an important indicator of poor prognosis in patients with esophageal cancer. However, a significant number of patients without LNM are still at high risk for recurrence. METHODS: We assessed prognostic factors in 143 patients without pathological LNM who were diagnosed with locally advanced esophageal squamous cell carcinoma (ESCC) and underwent neoadjuvant chemotherapy (NAC) or chemoradiotherapy (NACRT), followed by surgery. RESULTS: Using univariate and multivariate analyses of recurrence-free survival, carcinoembryonic antigen (CEA) levels (hazard ratio [HR]: 2.17, 95% confidence interval [CI]: 1.12-4.23, and p = 0.02) and neutrophil-to-lymphocyte ratio (NLR) (HR: 1.22, 95% CI: 1.04-1.43, and p = 0.02) were significant independent covariates. Furthermore, pretherapeutic LNM (HR: 1.94, 95% CI: 1.003-3.76, and p = 0.049), NACRT (HR: 3.29, 95% CI: 1.30-8.33, and p = 0.01), poorly differentiated tumors (HR: 2.52, 95% CI: 1.28-4.98, and p = 0.01), and lymphovascular invasion (LVI) (HR: 2.78, 95% CI: 1.27-6.09, and p = 0.01) were also significant independent covariates. The recurrence rates among patients with 0/1, 2, 3, and 4/5 poor prognostic factors were significantly different (5.0%, 25.0%, 35.7%, and 53.8%, respectively; p = 0.001); the survival rates were stratified among these prognostic groups. CONCLUSIONS: Pretherapeutic CEA and NLR levels, pretherapeutic LNM, NACRT, poorly differentiated tumors, and LVI were significantly correlated with survivals in patients without pathological LNM after neoadjuvant therapy and surgery. Postoperative therapy should be considered in patients with ESCC with several indicators of recurrence, even in those without pathological LNM who underwent surgery following neoadjuvant therapy.

PURPOSE: Various treatments are used for early postoperative recurrence of esophageal cancer, which has a poor prognosis. We evaluated the differences in outcomes and prognoses of each treatment modality between patients with early and late recurrence. METHODS: Early and late recurrence were defined as recurrence within and after six postoperative months, respectively. Of the 351 patients with esophageal squamous cell carcinoma who underwent R0 resection esophagectomy, 98 experienced postoperative recurrence (early recurrence, n = 41; late recurrence, n = 57). We evaluated the characteristics of patients with early and late recurrence and compared their treatment responses and prognoses. RESULTS: Regarding treatment responses for chemotherapy or immunotherapy, the objective response rate was not significantly different between the early- and late-recurrence groups. For chemoradiotherapy, the objective response rate was significantly lower in the early-recurrence group than in the late-recurrence group. The overall survival was significantly worse in the early-recurrence group than in the late-recurrence group. An analysis by treatment type showed that the early-recurrence group had significantly worse overall survival for chemoradiotherapy, surgery, and radiotherapy than the late-recurrence group. CONCLUSIONS: Patients with early recurrence had particularly poor prognoses with worse post recurrence treatment efficacy than those with late recurrence. The differences in the treatment efficacy and prognosis were particularly pronounced for local therapy.

BACKGROUND: It is occasionally difficult to diagnose cT3 or cT4b using imaging examinations for esophageal cancer. The optimal treatment strategy for borderline resectable esophageal squamous cell carcinoma (BR-ESCC) is unclear. METHODS: We included 131 patients with cT3 ESCC who received neoadjuvant chemoradiotherapy (NCRT) followed by surgery. The patients were classified as having definitive cT3 (D-cT3) or borderline resectable cT3 (BR-cT3), based on presence of undeniable adjacent organ invasion on pretreatment CT. Surgical outcomes and prognoses were compared among patients with D-cT3 and BR-cT3 tumors, and the risk factors for non-R0 resection were assessed. RESULTS: Ninety and 41 patients were classified as D-cT3 and BR-cT3, respectively. Although BR-cT3 had a significantly higher non-R0 resection rate than D-cT3 (D-cT3 3.7%; BR-cT3 14.6%), BR-cT3 was not correlated with shorter overall survival (OS) (D-cT3 5-year OS, 50.8%; BR-cT3 5-year OS 38.4%; p = 0.234). Conversely, non-R0 resection was significantly associated with poor OS (R0 resection 5-year OS 48.8%; non-R0 resection 5-year OS 22.2%; p = 0.031). Cox regression analysis of OS demonstrated that BR-cT3 was not a prognostic factor. In the analysis of risk factors for non-R0 resection, BR-cT3 (p = 0.027), suspected invasion of the trachea or bronchus (p = 0.046), and high SUVmax of the primary lesion after NCRT (p = 0.002) were risk factors. CONCLUSIONS: NCRT followed by surgery achieved a relatively high R0 resection rate and an almost equal overall survival rate for BR-cT3 compared with D-cT3 ESCC. Thus, NCRT followed by surgery is an effective treatment strategy for patients with BR-cT3 ESCC.

Accurate preoperative evaluation of lymph node (LN) metastasis is important for determining the treatment strategy for superficial esophageal cancer. Blood biomarkers, such as the neutrophil-lymphocyte, platelet-lymphocyte, and lymphocyte-monocyte ratios (NLR, PLR, and LMR, respectively), have clinical applications as predictors of LN metastasis for different cancers. Here, we investigated the use of these ratios as predictors of pathological LN metastasis and prognosis in patients with clinical stage T1N0M0 esophageal squamous cell carcinoma (ESCC). Patients (n = 185) with cT1N0M0 ESCC who underwent esophagectomy with R0 resection between April 2003 and August 2021 were enrolled. We investigated the ability of pretreatment NLR, PLR, and LMR to predict pathological LN metastasis. The optimal cutoff values of NLR, PLR, and LMR to predict pathological LN metastasis were 2.1, 122, and 4.8, respectively. Univariate and multivariate analyses revealed that the primary tumor length, depth of invasion, and NLR were significant predictors of LN metastasis. Furthermore, similar to the 5-year overall survival, the 5-year relapse-free survival was significantly better in the low NLR group than in the high NLR group. The NLR was the most useful predictor of pathological LN metastasis. Patients diagnosed with clinical stage I ESCC and with a high NLR require adequate LN dissection and may be good candidates for preoperative adjuvant therapy.

BACKGROUND: Although metastatic tumors in lymph nodes (LN) are potentially affected by neoadjuvant chemoradiotherapy (NCRT), the distribution of LN metastases of esophageal squamous cell carcinoma (ESCC) after trimodal therapy has never been sufficiently estimated. PATIENTS AND METHODS: We evaluated the distribution of LN metastases, relationships between LN metastases and radiation fields, risk factors for LN metastasis, and the influence of LN metastasis on the survival of 184 patients with ESCC who underwent NCRT followed by esophagectomy. RESULTS: Neoadjuvant chemoradiotherapy resulted in down-staged LN status in 74 (49.3%) patients. Pathological LN metastases were extensive in 177 LN stations in the cervical, mediastinal, and abdominal fields, and 162 (91.5%) metastases were located inside the radiation fields. Multivariate analysis showed that clinical N stage [N0 vs. 1/2/3: hazard ratio (HR), 2.69; 95% confidence interval (CI), 1.22-5.92; p = 0.01] and clinical response of primary tumor (complete vs. noncomplete: HR, 2.93; 95% CI, 1.50-5.69; p = 0.002) were statistically significant for pathological LN metastasis. Recurrence-free and overall survivals were significantly stratified according to the number of pathological LN metastases, associations between clinical and pathological LN metastases, and presence or absence of pathological LN metastases outside radiation field. CONCLUSIONS: About 50% of patients who were clinically diagnosed with LN metastasis before treatment were downstaged by NCRT, and their prognoses were relatively good. However, LN metastases were extensive at the cervical, mediastinal, and abdominal areas, even within the radiation field. Thus, systematic and adequate lymphadenectomy is required for ESCC treated by NCRT.

PURPOSE: Predicting the response to neoadjuvant chemoradiotherapy (NCRT) and the prognosis of esophageal squamous cell carcinoma (ESCC) is challenging. This study evaluated the potential of a preoperative computed tomography (CT) analysis for predicting the pathological response and survival of patients with ESCC who received trimodality therapy. METHODS: A total of 119 patients with cT3 or T4 ESCC who underwent surgery following NCRT between 2007 and 2019 were assessed. The CT-based parameters were measured with enhanced CT preoperatively, prior to and during treatment. Associations between these parameters and the pathologic response, as well as the prognosis, were examined. RESULTS: Pretreatment maximum CT value (p = 0.009), pretreatment mean CT value (p = 0.022), preoperative whole tumor volume (WTV, p = 0.003), preoperative largest cross section (LCS, p = 0.002), ΔLCS (pretreatment to preoperative, p = 0.004), ΔWTV (pretreatment to preoperative, p = 0.012), and Δmean CT value (pretreatment to preoperative, p = 0.012) of the primary lesion were significantly associated with a good pathological response. A Cox-regression analysis of recurrence-free survival (RFS) and overall survival (OS) showed that preoperative LCS was an independent CT-based predictor. RFS and OS were significantly higher at the optimal cut-off value of the preoperative LCS (p = 0.036 and p = 0.016, respectively). CONCLUSIONS: CT-based parameters are thus considered to be valuable predictors of the tumor response and survival after trimodality therapy for ESCC.

BACKGROUND: The degree of metabolic activity in tumor cells can be determined by 18F-fluorodeoxyglucose-positron emission tomography (FDG-PET). Associations between FDG uptake by primary tumors of locally advanced esophageal squamous cell carcinoma (ESCC) under trimodal therapy and the pathological features of such tumors have not been fully investigated. PATIENTS AND METHODS: We evaluated relationships between the maximal standardized uptake (SUVmax) in primary tumors on preoperative PET images and pathological features as well as cancer recurrence in 143 patients with ESCC who underwent neoadjuvant chemoradiotherapy (NCRT) followed by surgery. RESULTS: The post-SUVmax significantly differed after NCRT for ypT and ypN status, lymphatic invasion (LI), venous invasion (VI), and recurrence. Furthermore, the %ΔSUVmax (rate of decrease between before and after NCRT) for LI, VI, and recurrence significantly differed. Univariate and multivariate analyses selected post-SUVmax and %ΔSUVmax as independent preoperative predictors of recurrence-free survival [hazard ratio (HR) 1.46; 95% confidence interval (CI) 1.24-1.72 and HR 0.97; 95% CI 0.96-0.99, respectively; p < 0.001 for both]. Recurrence-free and overall survival were significantly stratified according to optimal SUVmax cutoffs for predicting recurrence (post- and %ΔSUVmax: 2.8 and 70, respectively). CONCLUSIONS: The post- and %ΔSUVmax of primary tumors were significantly associated with the pathological features and recurrence of ESCC under trimodal therapy. Therefore, FDG-PET can preoperatively predict the degree of aggressive tumor behavior in ESCC under trimodal therapy.

BACKGROUND: The evaluation of treatment outcomes and detection of prognostic factors after recurrence are very important for tailoring optimal therapies for individual patients with recurrent esophageal cancer. METHODS: We reviewed 133 patients in whom esophageal squamous cell carcinoma (ESCC) recurred after curative surgery, and assessed recurrence patterns, treatment outcomes and prognostic factors. RESULTS: Recurrence in 57 (42.9%), 54 (40.6%) and 22 (16.5%) patients was locoregional, distant and combined, respectively. The median amounts of elapsed time until recurrence and median survival after recurrence for all patients were 9.1 and 8.3 months, respectively. Univariate and multivariate analyses selected time to recurrence (hazard ratio [HR], 0.98; 95% confidence interval [CI], 0.97-0.999; p = 0.04), recurrence location (locoregional vs. distant: HR, 1.63; 95% CI, 1.03-2.61; p = 0.04), number of organs with recurrence (1 vs. 3: HR, 3.49; 95% CI, 1.23-9.87; p = 0.02) and treatment after recurrence (best supportive care, [BSC] vs. chemotherapy [CT] or radiation therapy [RT]: HR, 0.37; 95% CI, 0.15-0.94; p = 0.04; BSC vs. CT and RT: HR, 0.50; 95% CI, 0.26-0.94; p = 0.03; BSC vs. surgery: HR, 0.47; 95% CI, 0.25-0.88; p = 0.02) as independent factors for survival after recurrence. Seventeen (12.8%) patients who had localized lymph node recurrence and lung oligometastasis and received multidisciplinary therapy after recurrence survived for >3 years thereafter. CONCLUSION: Despite the poor survival of patients with ESCC and early or distant recurrence or recurrence in ≥3 recurrent organs, appropriate multimodal therapies should be tailored for individual patients with recurrent ESCC.

BACKGROUND: Intensive trimodality therapy is needed for locally advanced esophageal squamous cell carcinoma (ESCC). However, some patients develop recurrence and die of cancer even after trimodality therapy. METHODS: We evaluated prognostic factors based on data from 125 patients with ESCC who underwent neoadjuvant chemoradiotherapy (NCRT) comprising concurrent chemotherapy and 40 Gy of radiation, followed by curative-intent esophagectomy. RESULTS: Thirty-four (27.2%) patients achieved a pathological complete response (pCR) after NCRT. The 5-year recurrence-free (RFS) and overall survival (OS) rates of all patients were 49.2 and 52.9%, respectively, and were significantly better for patients with pCR than without pCR (p = 0.01 and 0.02, respectively). Univariate and multivariate analyses selected performance status [PS 0 vs. 1: hazard ratio (HR) 2.05; 95% confidence interval (CI) 1.30-4.84; p = 0.01] and ypN (0 vs. 1: HR 2.33; 95% CI 1.12-4.84; p = 0.02; 0 vs. 2/3: HR 3.73; 95% CI 1.68-8.28; p = 0.001) as independent covariates for RFS. Furthermore, PS (0 vs. 1; HR 2.94; 95% CI 1.51-5.72; p = 0.002) and ypN (0 vs. 1; HR 2.26; 95% CI 1.09-4.69; p = 0.03; 0 vs. 2/3: HR 3.90; 95% CI 1.79-8.48; p = 0.001) were also independent covariates for OS. CONCLUSIONS: Performance status 1 and ypN+ were significantly associated with a poor prognosis after trimodality therapy for ESCC.

BACKGROUND: Elevated preoperative serum C-reactive protein (CRP) levels are reportedly associated with a poor prognosis for patients with various types of malignant tumors. However, the impact of postoperative CRP levels on the prognosis of patients with esophageal cancer remains unknown. The present study aims to clarify the prognostic significance of postoperative CRP levels on the survival of patients with esophageal cancer. METHODS: We reviewed the records of consecutive 202 patients with thoracic esophageal squamous cell carcinoma who underwent transthoracic esophagectomy. We measured serum CRP levels on postoperative days (PODs) 1, 2, 3, 5 and 7 and evaluated the relationships between postoperative CRP levels and survival. RESULTS: The findings of Cox regression analyses suggested that elevated CRP levels on POD 3, 5 and 7 were associated with poor recurrence-free survival (RFS). We divided CRP levels on POD 7 into three tertiles and found that RFS could be clearly stratified, being the poorest (p < 0.001) in the highest tertile (high CRP). The trend was similar even in patients with or without infectious complications and with or without advanced pathological stage. Multivariate analysis showed that pathologically advanced stage (Hazard ratio [HR], 5.14; 95% confidence interval [CI] 2.67-9.87; p < 0.001) and high CRP (HR, 2.27; 95% CI 1.3-3.96; p = 0.004) were independent predictors of RFS. CONCLUSION: Postoperative CRP levels could predict the prognosis of patients with esophageal cancer. We propose that the clinical course of postoperative CRP level should be carefully monitored as a predictor of survival.

We report a case of small intestinal adenocarcinoma treated with laparoscopic surgery. A 70-year-old woman had abdominal pain and epigastralgia. There were no abnormal findings on upper and lower endoscopy. The symptoms continued for 4 months after endoscopy, so she presented to our hospital. After CT examination, small bowel cancer with ileus was suspected. An ileus tube was inserted to relieve the bowel pressure and she was diagnosed with ileum cancer by enteroscopy. Laparoscopic surgery was performed and the pathological stage was determined as pStage â ¢a. She was treated with oral chemotherapy (UFT plus LV) and had no recurrence 6 months after surgery.

The aim of this study was to compare the efficacy of self-expandable metallic stent (SEMS) and transanal tube as preoperative treatments for left-sided obstructive colon cancer. Forty-three patients (the SEMS group: 28 cases, the tube group: 15 cases) were included in this study. Clinicopathological data (age, sex, tumor location, depth, histological type, stage) were comparable between the 2 groups. In addition, there was no difference in intestinal decompression rate between the SEMS group and the tube group (technical success rate: 100% vs 86.7%, clinical success rate: 92.8% vs 73.3%, complication rate: 7.1% vs 0%). A significantly higher number of patients in the SEMS group underwent laparoscopic surgery because of difference of historical background. However, no significant difference was observed between the 2 groups in postoperative outcome(complication rate, hospital stay duration). SEMS insertion had several benefits compared to transanal tube placement, such as the resumption of oral intake because of rapid resolution of obstruction and easier management because SEMSs do not require washing. SEMS insertion could be a safe and effective bridge to subsequent surgery in patients with left-sided obstructive colon cancer.

We report a case of radical resection of rectal cancer with multiple liver and lung metastases after preoperative chemotherapy. A 54-year-old woman presented with abdominal pain and loss of body weight due to rectal cancer with multiple liver and lung metastases. Therefore, the patient received 14 courses of bevacizumab+mFOLFOX6, and 7 courses of panitumumab+FOLFIRI. After the chemotherapy, the size of the distant metastases reduced by 62% on computed tomography, according to RECIST. Due to the reduction in size, a conversion surgery was attempted. First, an abdominal operation with laparoscopy was performed, and 2 months later an operation to resect the lung metastases via thoracoscopy was performed. Currently, 3 months after surgery, the patient is alive, without recurrence.

A 70-year-old woman who complained of abdominal pain and a prolapsed tumor from the anus was diagnosed with an intestinal obstruction resulting from anal canal cancer. Computed tomography (CT) and magnetic resonance imaging revealed a huge tumor (11×5×12 cm) invading the vagina and levator ani muscle. Enlarged inguinal lymph nodes on both sides indicated metastasis. The clinical stage was T4b (vagina, levator ani muscle, and pudenda) N0H0M1a (LYM), stage IV (Japanese Classification of Colorectal Carcinoma: 8th edition). As curative resection was not possible, a transvers colostomy was performed to relieve the intestinal obstruction. This was followed by chemoradiotherapy (45 Gy/1.8 Gy×25; TS-1, 80 mg/body for 2 weeks and a 1-week interval, for 2 courses) and up to 10 courses of Bev+mFOLFOX6 continuously. After this regimen, there was a remarkable reduction in tumor size. Positron emission tomography-CT revealed no FDG uptake in the primary rectal site or inguinal lymph nodes, but a maximum standardized uptake value (SUVmax) of 6.3 was detected in the vagina. Six weeks after chemotherapy, the patient underwent a pelvic exenteration including resection of the vagina, bladder, and pudenda. The pathological stage was yp T4b (vagina) N0H0M0, stageâ ¡. Curative resection was performed, and the patient had a Grade 2 pathological response after chemoradiotherapy.

A 77-year-old-woman, whose chief complaint was anemia, was referred to our hospital and diagnosed with advanced gastric cancer with liver metastasis and lymph node metastasis.Gastrointestinal endoscopy showed a tumor on the lesser curvature of the gastric corpus.Histologically, biopsy specimens indicated adenocarcinoma with genetic amplification of human epidermal growth factor receptor type 2.Computed tomography and magnetic resonance imaging showed lymph node metastasis and liver metastasis.The patient received a total gastrectomy and a partial liver resection after combination chemotherapy consisting of capecitabine, cisplatin, and trastuzumab.Histopathological examination of a resected specimen showed a minute residual cancer nest at the subserosa of the stomach and lymph node metastasis, but no liver metastasis. This combined modality therapy can be considered an effective treatment for gastric cancer with liver metastasis, and we hope that it will be established as a standard therapy.

Background/Aim: This study aimed to evaluate the long-term prognosis of definitive chemoradiotherapy and clinical features of postoperative lymph node (LN) recurrence after curative resection of thoracic esophageal squamous cell cancer (ESCC). Patients and Methods: A total of 586 patients who underwent radical resection of ESCC at the Hiroshima University Hospital from January 2000 to December 2019 were reviewed retrospectively. This study analyzed the clinical characteristics of 54 patients who developed recurrence in a solitary LN by comparing them to 182 patients who experienced total recurrence. Additionally, we analyzed the prognostic factors of 50 patients who received chemo-radiotherapy (CRT). Results: The results revealed a tendency for a higher incidence of solitary LN recurrence in cases of early esophageal cancer and upper thoracic esophageal cancer among all recurrence cases. The 3-, 5-, and 7-year overall survival (OS) rates were 40.5%, 37.8% and 34.6%, respectively, with a median survival time of 27.9 months. Univariate analysis of OS factors, such as age, depth of the primary tumor at the initial surgery, time to LN recurrence after surgery, site of LN recurrence, and the number of the regional LNs with recurrence showed no significant impact on OS. Conclusion: Approximately 35% of patients with ESCC who experienced LN recurrence after curative resection achieved long-term survival through CRT. Despite the absence of identifiable prognostic factors, CRT proves to be a valuable initial treatment option for LN recurrence.
RESUMEN
Purpose: Various blood cell parameters have been identified as predictive markers of tumor responses and the survival of patients with cancer treated with immune checkpoint inhibitors. The purpose of this study is to assess the ability of various blood cell parameters to predict therapeutic effects and survival in patients with esophageal squamous cell carcinoma (ESCC) treated with nivolumab monotherapy. Patients and Methods: We evaluated neutrophil-to-lymphocyte (NLR), platelet-to-lymphocyte (PLR) and lymphocyte-to-monocyte (LMR) ratios as predictive markers of patients' survival and effects of nivolumab monotherapy after one or more prior chemotherapies for unresectable advanced or recurrent ESCC. Results: The objective response and disease control rates were 20.3% and 47.5%, respectively. The LMRs before, and 14 and 28 days after nivolumab initiation were significantly higher in patients with complete response (CR)/partial response (PR)/stable disease (SD) than those with progressive disease (PD). The NLRs at 14 and 28 days after nivolumab initiation were significantly lower in patients with CR/PR/SD than with PD. The optimal cutoffs for these parameters significantly discriminated patients with CR/PR/SD and PD. Univariate and multivariate analyses identified pretreatment NLRs as a significant independent factor for progression-free and overall survival (hazard ratio [HR]: 1.19, 95% confidence interval [CI]: 1.07-1.32, and HR 1.23, 95% CI: 1.11-1.37, respectively; p ≤ 0.001 for both). Conclusion: The pretreatment LMRs, and NLR and LMR at 14 and 28 days after starting nivolumab monotherapy were significantly associated with the clinical therapeutic effect. The pretreatment NLR was significantly associated with patients' survival. These blood cell parameters before and during the early days of nivolumab monotherapy can help to identify patients with ESCC who would most likely benefit from nivolumab monotherapy.
RESUMEN
Background: Esophageal fistula (EF) is a serious complication in patients with cT4b esophageal squamous cell carcinoma (ESCC) with adjacent organ involvement. Among EFs, aortoesophageal fistula (AEF), forming a fistula with the aorta, could be fatal. This study aimed to identify the risk factors for AEF in patients with cT4b ESCC with obvious or suspected aortic invasion who underwent definitive radiotherapy (DRT). Methods: Forty-four patients with cT4b ESCC with obvious or suspected invasion to the aorta who underwent DRT were included. Blood tests and computed tomography (CT) findings before and after DRT were compared between the patients with and without AEF to identify the potential risk factors for AEF. Results: Nine patients (20.5%) developed AEF after DRT. Comparing between patients with and without AEF, pre-DRT white blood cell counts and post-DRT C-reactive protein (CRP) levels were significantly higher in patients with AEF. Furthermore, pre-DRT CT findings were similar between the two groups. However, post-DRT CT findings demonstrated significantly larger picus angle and lower esophageal wall thickness on the aortic side in patients with AEF. Multivariate analysis identified elevated post-DRT CRP levels [<3.3 versus ≥3.3 mg/dL; odds ratio (OR): 30.7; 95% confidence interval (CI): 2.92-323.2; P=0.004] and esophageal wall thinning on post-DRT CT scans (>6 versus ≤6 mm; OR: 13.2; 95% CI: 1.24-140.1; P=0.033) as risk factors for AEF. Conclusions: We found that post-DRT esophageal wall thinning on the aortic side, as observed on CT scans, and elevated CRP levels were predictive factors for AEF in patients with cT4b ESCC with obvious or suspected invasion to the aorta.
