Percent vital capacity predicts postoperative sarcopenia after esophagectomy in initially nonsarcopenic esophageal cancer patients: a retrospective cohort study.

PURPOSE: The development of sarcopenia after esophagectomy is reported to affect the outcomes of patients with esophageal cancer (EC); however, the characteristics of patients likely to be predisposed to postoperative sarcopenia have not been defined. This study explores the associations between preoperative respiratory function and surgery-induced sarcopenia in EC patients confirmed as nonsarcopenic preoperatively. METHODS: The subjects of this retrospective review were 128 nonsarcopenic patients who underwent esophagectomy for EC. We took body composition measurements and performed physical function tests 3 and 6 months postoperatively, to establish whether sarcopenia was present, according to the 2019 Asian Working Group for Sarcopenia guideline. We defined patients with surgery-induced sarcopenia as those with evidence of the development of sarcopenia within 6 months postoperatively or those with documented sarcopenia at 3 months but who could not be evaluated at 6 months. RESULTS: Surgery-induced sarcopenia developed in 19 of the 128 patients (14.8%), which correlated significantly with the preoperative %VC value (p < 0.01), but not with the preoperative FEV1.0% value. We set the lower quartile %VC value (91%) as the cut-off for predicting surgery-induced sarcopenia. A low %VC was independently associated with surgery-induced sarcopenia (odds ratio: 5.74; 95% confidence interval: 1.99-16.57; p < 0.01). CONCLUSIONS: Based on the findings of this study, %VC was a simple but valuable factor for predicting sarcopenia induced by esophagectomy.

Low pretherapy skeletal muscle mass index is associated with an increased risk of febrile neutropenia in patients with esophageal cancer receiving docetaxel + cisplatin + 5-fluorouracil (DCF) therapy.

PURPOSE: Docetaxel + cisplatin + 5-fluorouracil (DCF) therapy, a frequently prescribed regimen for esophageal cancer, is associated with a high risk of febrile neutropenia (FN). This study investigated whether a low skeletal muscle mass index (SMI) is an independent risk factor for FN. METHODS: This retrospective, observational study investigated the SMI of patients with esophageal cancer who received DCF therapy between March 2018 and July 2020. Based on the Asian sarcopenia criteria, patients were divided into two groups: high and low SMI (SMI of < 7.0 and 5.7 kg/m2 for males and females, respectively). The incidence of FN was then compared between the two groups. RESULTS: Thirty-nine patients (20 and 19 in the high- and low-SMI groups, respectively) were included in this study. The incidence of FN was significantly higher in the low-SMI group (63.2% vs. 20.0%, P = 0.006). Univariable and multivariable logistic regression analyses revealed that a low SMI was an independent risk factor for FN (odds ratio, 7.178; 95% confidence interval, 1.272-40.507; P = 0.026). In addition, the frequency of dose reduction in DCF therapy was significantly higher in the low-SMI group (68.4% vs. 35.0%, P = 0.037). CONCLUSION: Low SMI is an independent risk factor for FN in patients with esophageal cancer receiving DCF therapy.

Liver retraction using an L-shaped retractor during sleeve gastrectomy.

PURPOSE: The Nathanson liver retractor (NLR) and the snake liver retractor (SLR) are commonly used in bariatric surgery and their use is associated with some disadvantages. We developed an L-shaped liver retractor (LLR) and herein evaluated its efficacy and safety. METHODS: The present retrospective study enrolled patients undergoing sleeve gastrectomy in our department between June 2014 and December 2020. The patients were divided into three groups according to the liver retractor used (LLR, SLR or NLR) for a comparative analysis of the efficacy and safety of the devices. The procedural time (PT) of each retractor type, defined as the time from retractor insertion to liver fixation, was compared. RESULTS: In total, 140 patients successfully underwent laparoscopic sleeve gastrectomy. The LLR, SLR and NLR were used in 37, 91, and 12 of these patients, respectively. The PT for the LLR was the shortest. AST/ALT elevation was significantly more frequent in the NLR group than in the SLR group and tended to be less frequent in the LLR group in comparison to the NLR group (p = 0.09). The length of hospital stay in the NLR group was significantly longer in comparison to the LLR group. CONCLUSION: Our study suggested that the LLR was superior to the conventional liver retractors used in sleeve gastrectomy.

A case of late postoperative intra-abdominal hemorrhage developing 13 months after laparoscopic sleeve gastrectomy.

A 29-year-old male patient underwent laparoscopic sleeve gastrectomy (LSG) for morbid obesity and was discharged without any complications. Thirteen months later, he visited the emergency room with epigastric pain. A few hours before onset, he had had a larger-than-usual meal and vomited afterwards. Enhanced abdominal computed tomography revealed a hematoma 127 × 63 mm in diameter around the stomach. Angiography revealed no extravasation or pseudoaneurysm. Upper gastrointestinal endoscopy found no ulcers or abnormality of the stapler line scar from the LSG. The patient's vital signs were stable, and his hemoglobin had not fallen below the previous day's value. Conservative treatment was therefore chosen. The patient was discharged in stable condition after 11 days of hospitalization. However, the exact source of the hemorrhage was unable to be detected on the imaging findings. In view of his clinical course and the hematoma location, omental vessels were suspected of being the source of the hemorrhage.

The type of gastrectomy affects skeletal muscle loss and the long-term outcomes of elderly patients with gastric cancer: a retrospective study using computed tomography images.

PURPOSE: Sarcopenia is common in elderly gastrectomized patients and a known risk factor for postoperative complications and poor overall survival. However, the long-term outcomes of skeletal muscle loss after gastrectomy and the differences in outcomes of different gastrectomy procedures remain unclear. METHODS: The subjects of this retrospective study were 136 patients who underwent various gastrectomy procedures for early gastric cancer, namely: total gastrectomy (TG; n = 20), proximal gastrectomy (PG; n = 16), distal gastrectomy (DG; n = 60), and pylorus-preserving gastrectomy (PPG; n = 40). Skeletal muscle volume (SMV), calculated as the skeletal muscle index (SMI), was measured using cross-sectional computed tomography (CT) scans preoperatively and then 1, 2, and 3 years after gastrectomy. RESULTS: Sarcopenia developed from 2 years onwards in all the patients who underwent TG. The SMI and sarcopenia prevalence after gastrectomy deteriorated over time. Multivariate analysis revealed that TG and PG were significant risk factors for skeletal muscle loss in postoperative years 1 and 3. A decrease in the SMI after TG or PG was most remarkable in elderly patients. CONCLUSIONS: The type of gastrectomy affects skeletal muscle loss in the long term. Elderly patients who undergo TG or PG are at high risk of severe skeletal muscle loss.

A case of disseminated carcinomatosis of the bone marrow from gastric cancer developing rapidly after a gastrectomy.

BACKGROUND: Disseminated carcinomatosis of the bone marrow (DCBM) is often associated with disseminated intravascular coagulation (DIC) and a poor prognosis. Moreover, the timing of the diagnosis varies. We presented herein the first report of a case of DCBM from gastric cancer that developed rapidly after a gastrectomy. CASE PRESENTATION: A 42-year-old male patient was referred to us for gastric cancer. Preoperative laboratory tests were normal. Abdominal computed tomography (CT) revealed no obvious bone metastasis, and he underwent a laparoscopic distal gastrectomy. On postoperative day (POD) 1, laboratory data indicated severe thrombocytopenia. Postoperative bleeding requiring reoperation was found. Afterwards, he complained of lower back pain. His ALP and LDH gradually became elevated. On POD 8, DIC was diagnosed. CT and bone scintigraphy showed multiple, widespread bone metastases. Based on these findings, DCBM from gastric cancer was diagnosed. Systemic chemotherapy was started on POD 12. The DIC subsided during the first course, and he was discharged on POD 21. The patient died of tumor progression 7 months later. CONCLUSION: When thrombocytopenia is observed immediately after a gastrectomy for gastric cancer, the possibility of DCBM should be considered.

One-by-One Comparison of Lymph Nodes Between 18F-FDG Uptake and Pathological Diagnosis in Esophageal Cancer.

PURPOSE: Esophagectomy with extended lymph node (LN) dissection is a standard treatment for resectable esophageal cancer to prevent recurrence, but severe, potentially life-threatening postoperative complications are still important issues. Accurate diagnosis of LN metastases would enable the decision to dissect or leave the LNs in regions with high risk of complications. Advancements in intraoperative gamma probe and radioactivity detectors have made intraoperative navigation surgery possible using a radiotracer as a marker. F-FDG is one such candidate markers, and the diagnostic power of FDG through counting the radioactivity close to each LN should be elucidated. MATERIALS AND METHODS: In 20 patients, 1073 LNs including 38 metastatic LNs were prospectively investigated. Preoperative FDG PET was performed on the same day before esophagectomy and visually surveyed in each LN station to identify abnormal uptake. The FDG radioactivity of each individual dissected LN was measured by a well-type counter, and the pathological diagnosis was compared with LN radioactivity on a one-by-one basis and with the preoperative FDG PET findings for each LN station. RESULTS: Lymph node station-based analysis showed a sensitivity and specificity of 28.6% and 96.7%, respectively. One-by-one LN-based analysis using a cutoff value obtained from the receiver operating characteristic curve showed a sensitivity and specificity of 94.7% and 78.7%, respectively, demonstrating higher accuracy compared with the use of LN weight or the shortest diameter. CONCLUSIONS: The FDG uptake by each LN is a potentially useful marker for navigation surgery in esophageal cancer and has higher accuracy than LN weight or diameter.

Preoperative Exercise Habits are Associated with Post-gastrectomy Complications.

BACKGROUND: Sarcopenia is reportedly associated with postoperative complications of gastrectomy, which would presumably be affected by exercise habits aimed at maintaining muscle quantity and quality. However, the potential benefits of exercise habits have yet to be clarified. METHODS: We included 178 patients undergoing gastrectomy in this study. Postoperative complications above grade 2 according to the Clavien-Dindo classification were regarded as clinically significant. Patients were classified according to exercise quantity employing the International Physical Activity Questionnaire Short Form and relationships between exercise habits and complications were investigated. RESULTS: On univariate analysis, low exercise habits (p = 0.008) and total gastrectomy (p = 0.004) were significantly associated with morbidity after gastrectomy. Although severe comorbidity (p = 0.095) and combined resection (p = 0.064) tended to be associated with complications, multivariate analysis demonstrated only low levels of exercise (Odds ratio = 2.42, p = 0.014) and total gastrectomy (Odds ratio = 3.67, p = 0.028) to be independently associated with postoperative complications. Anastomotic leakage (p = 0.028) and systemic complications (p = 0.006), especially pneumonia, were significantly more frequent in the low exercise group. CONCLUSIONS: Preoperative exercise habits independently affected short-term postoperative outcomes. Our results raise the possibility that exercise intervention would reduce the morbidity experienced by gastrectomy patients.

Relationships among body composition, muscle strength, and sarcopenia in esophageal squamous cell carcinoma patients.

PURPOSE: Relationships among body composition indices assessed by various modalities remain to be addressed in patients with esophageal squamous cell carcinoma (ESCC), in whom being underweight is more strikingly prevalent than in those with other malignancies. We investigated the relationships of body composition parameters with the sarcopenia prevalence of ESCC patients. METHODS: In this prospective study, we analyzed preoperative data obtained from 75 ESCC patients undergoing esophagectomy. Body composition data included body mass index (BMI), skeletal muscle index (SMI) assessed by computed tomography, and parameters calculated by bioelectrical impedance analysis (skeletal muscle mass (SMM), body fat mass). Muscle strength was evaluated by handgrip strength (HGS). Sarcopenia was defined as having both low SMI and low HGS. RESULTS: The median BMI value was 22.5 (range 15.2-28.7) in our ESCC cohort. BMI correlated significantly with fat mass (r = 0.84, P < 0.001), SMM (r = 0.57, P < 0.001) and SMI (r = 0.49, P < 0.001). Similarly, SMI showed a significant correlation with SMM (r = 0.45, P < 0.001). Meanwhile, HGS was highly correlated with SMM (r = 0.67, P < 0.001), while showing significant but weak associations with both BMI and SMI (r = 0.33, 0.34, respectively, P < 0.001). Notably, sarcopenia prevalence differed markedly according to BMI category; 28.6%, 12.2%, and 0% in the low (< 20), medium (20-25), and high (> 25) BMI groups, respectively. CONCLUSIONS: BMI reflects comprehensive information on body composition in ESCC patients, although its correlation with muscle mass and muscle strength was moderate. Decreased BMI might serve as an indicator for sarcopenia in this population, in which the presence of sarcopenic obesity is rare.

Perioperative fluid dynamics evaluated by bioelectrical impedance analysis predict infectious surgical complications after esophagectomy.

BACKGROUND: Transthoracic esophagectomy, among the most invasive surgeries, is highly associated with postoperative infectious complications which adversely affect postoperative management including fluid dynamics. The aim of the study is to evaluate the utility of perioperative bioelectrical impedance analysis (BIA) measurements for the patients after transthoracic esophagectomy. METHOD: Multi-frequency BIA measurements were conducted in 24 patients undergoing transthoracic esophagectomy preoperatively, at 1 h after surgery, and twice daily for the following 7 days. The amounts of extracellular water (ECW), internal cellular water (ICW), total body water (TBW), and fat-free mass (FFM) were calculated. Changing trends in variables were analyzed, and the patients were subdivided according to the presence of infectious surgical adverse events to identify differences in fluid dynamics. RESULTS: ECW was the major body fluid compartment showing an increase after surgery, and peaked on postoperative day (POD) 2. Twelve patients experienced infectious complications. The peaks of changes in ECW and ECW/TBW appeared earlier and their values at the highest peak were significantly lower in the group without infectious complications on POD 2. The ICW/FFM value showed a mild decrease as compared to POD1 and then gradually recovered. It was significantly lower even before surgery and showed the most significant stratification on POD2. ECW/TBW of 48% and ICW/FFM of 37% on POD2 were predictive cut-off values for infectious adverse events with high area-under receiver operating characteristic (ROC) curves: 0.80 or higher. CONCLUSION: BIA measurements are useful for monitoring fluid retention and may predict infectious complications in the early phase after transthoracic esophagectomy.

A surgical case of radiotherapy induced esophageal perforation accompanying pyogenic spondylodiscitis: a case report.

BACKGROUND: Stereotactic body radiotherapy has been a treatment choice for lung cancer, especially in medically inoperable patients. However, the acute and late toxicity to adjacent organs have been reported as an uncommon but severe adverse effect. CASE PRESENTATION: A 65-year-old male was presented with his back pain and pyrexia. He had been followed up for non-small-cell lung cancer, which was treated by the stereotactic body radiotherapy 4 years prior to the current visit. The endoscopy revealed an esophageal perforation on its left side in the upper thoracic locus. Because of his poor lung function, he was managed by the conservative treatment. After 3 months, his back pain recurred with developing paraplegia in the lower extremities. The MRI revealed an abscess formation at the posterior side of the upper thoracic esophagus which destroyed the vertebral body and compressed the spinal cord. Laminectomy and two-stage operation-the first stage, nontransthoracic esophagectomy, cervical and transhiatal approach using mediastinoscope and laparoscope, and the second stage, esophageal reconstruction-were performed. CONCLUSION: This complex disease status was successfully managed by the orthopedic surgery followed by a two-stage esophagectomy without transthoracic approach.

The influence of carmustine wafer implantation on tumor bed cysts and peritumoral brain edema.

The development of perifocal edema and tumor bed cyst has been reported after implantation of biodegradable carmustine wafers for the treatment of malignant gliomas. We retrospectively evaluated these changes in a series of patients; 19 consecutive patients with malignant glioma who received carmustine wafer implantation at our hospital from January 2013 through July 2013, and 28 patients who underwent surgery prior to our institution's initiation of carmustine wafer implantation, as historical controls. The volume of the tumor bed cyst and perifocal edema was calculated on MRI acquired at four time points: ⩽72hours after surgery for baseline, and at 1-4, 5-8, and 9-12weeks after surgery. The volume of the tumor bed cyst in the wafer group increased significantly relative to the control group at all time points (p=0.04). Opening of the ventricle was inversely correlated with enlargement of the tumor bed cyst in the wafer group (p=0.04). The change in the volume of perifocal edema in the wafer group was not significantly different (p=0.48), but exhibited a considerable increase in patients with anaplastic oligodendroglioma relative to glioblastoma patients in the wafer group (p=0.01). We demonstrated significant enlargement of the tumor bed cyst volume after carmustine wafer implantation, as well as the development of marked perifocal edema in patients with anaplastic oligodendroglioma.

Methionine Uptake and Required Radiation Dose to Control Glioblastoma.

PURPOSE: The purpose of this study was to retrospectively assess the feasibility of radiation therapy planning for glioblastoma multiforme (GBM) based on the use of methionine (MET) positron emission tomography (PET), and the correlation among MET uptake, radiation dose, and tumor control. METHODS AND MATERIALS: Twenty-two patients with GBM who underwent MET-PET prior to radiation therapy were enrolled. MET uptake in 30 regions of interest (ROIs) from 22 GBMs, biologically effective doses (BEDs) for the ROIs and their ratios (MET uptake:BED) were compared in terms of whether the ROIs were controlled for >12 months. RESULTS: MET uptake was significantly correlated with tumor control (odds ratio [OR], 10.0; P = .005); however, there was a higher level of correlation between MET uptake:BED ratio and tumor control (OR, 40.0; P < .0001). These data indicated that the required BEDs for controlling the ROIs could be predicted in terms of MET uptake; BED could be calculated as [34.0 × MET uptake] Gy from the optimal threshold of the MET uptake:BED ratio for tumor control. CONCLUSIONS: Target delineation based on MET-PET was demonstrated to be feasible for radiation therapy treatment planning. MET-PET could not only provide precise visualization of infiltrating tumor cells but also predict the required radiation doses to control target regions.

Epilepsy in patients with gliomas: incidence and control of seizures.

Brain tumor-related epilepsy (BTRE) is a unique condition that is distinct from primary epilepsy. The aim of this retrospective study was to clarify the epidemiology and results of treatment of BTRE in a single institution. From a database of 121 consecutive patients with supratentorial gliomas treated at Chiba Cancer Center from 2006-2012, the incidence and control of seizures before and after surgery were retrospectively evaluated. Epilepsy occurred in 33.9% of patients before surgery. All patients received prophylactic anti-epileptic drugs (AED) during surgery; however, seizures occurred in 9.1% of patients within the first postoperative week. During follow-up, seizures occurred in 48.3% of patients. The overall incidence of seizures was 73.7% in patients with World Health Organization Grade II gliomas, 66.7% in those with Grade III and 56.8% in those with Grade IV gliomas. Levetiracetam was very well tolerated. However, carbamazepine and phenytoin were poorly tolerated because of adverse effects. AED were discontinued in 56 patients. Fifteen of these patients (26.8%) had further seizures, half occurring within 3 months and 80% within 6 months of AED withdrawal. No clinical factors that indicated it was safe to discontinue AED were identified. The unpredictable epileptogenesis associated with gliomas and their excision requires prolonged administration of AED. To maintain quality of life and to safely and effectively control the tumor, it is necessary to select AED that do not adversely affect cognitive function or interact with other drugs, including anti-cancer agents.

Frequency of brain metastases in non-small-cell lung cancer, and their association with epidermal growth factor receptor mutations.

BACKGROUND: The brain is a frequent site of metastases from non-small-cell lung cancer (NSCLC). We analyzed the frequency of brain metastases (BMs) from NSCLC in the era of magnetic resonance images, and evaluated the correlation between epidermal growth factor receptor (EGFR) mutations and BMs among East Asian patients. METHODS: Frequency, number, and size of BMs, and survival of 1,127 NSCLC patients were retrospectively reviewed. Mutation status of EGFR was evaluated in all cases, and its association with BMs was statistically evaluated. RESULTS: EGFR mutations were found for 331 cases (29.4 %). BM was the cause of primary symptoms for 52 patients (4.6 %), and found before initiation of treatment for 102 other patients (9.1 %); In addition to these 154 patients, 107 patients (9.5 %) developed BMs, giving a total of 261 patients (23.2 %) who developed BMs from 1,127 with NSCLC. BM frequency was higher among EGFR-mutated cases (31.4 %) than EGFR-wild cases (19.7 %; odds ratio: 1.86; 95 % confidence interval (CI) 1.39-2.49; P < 0.001). BMs from EGFR-mutated NSCLC were small, but often became disseminated. EGFR mutations accounted for 39.9 % of BMs, but patient survival after BMs was significantly longer for EGFR-mutated cases than for EGFR-wild cases (hazard ratio: 2.23; 95 % CI 1.62-3.10; P < 0.001). CONCLUSIONS: Patients with EGFR-mutated NSCLC were more likely to develop BMs, but apparently also survived longer after BMs.

Levetiracetam versus phenytoin for seizure prophylaxis during and early after craniotomy for brain tumours: a phase II prospective, randomised study.

OBJECTIVE: Phenytoin (PHT) is routinely used for seizure prophylaxis in patients with brain tumours during and after craniotomy, despite incomplete evidence. We performed a prospective, randomised study to investigate the significance of prophylactic use of levetiracetam (LEV), in comparison with PHT, for patients with supratentorial tumours in the perioperative period. METHODS: Patients were randomised to receive LEV, 500 mg/body every 12 h until postoperative day 7, or PHT, 15-18 mg/kg fosphenytoin followed by 125 mg PHT every 12 h until postoperative day 7. The primary end point was the occurrence of seizures, and secondary end points included the occurrence of haematological and non-haematological adverse events. RESULTS: One hundred and forty-six patients were randomised to receive LEV (n=73) or PHT (n=73). The incidence of seizures was significantly less in the LEV group (1.4%) compared with the PHT group (15.1%, p=0.005), suggesting benefit of LEV over PHT. The observed OR for being seizure free in the LEV prophylaxis group relative to the PHT group was 12.77 (95% CI 2.39 to 236.71, p=0.001). In a subgroup analysis of patients who did not have seizures before craniotomy, similar results were demonstrated: the incidence of seizures was 1.9% (LEV) and 13.8% (PHT, p=0.034), and OR was 8.16 (95% CI 1.42 to 154.19, p=0.015). LEV was completed in all cases, although PHT was withdrawn in five patients owing to liver dysfunction (1), skin eruption (2) and atrial fibrillation (2). CONCLUSIONS: Prophylactic use of LEV in the perioperative period is recommended because it is safe and significantly reduces the incidence of seizures in this period. TRIAL REGISTRATION NUMBER: UMIN13971.

Phase 2 trial of hypofractionated high-dose intensity modulated radiation therapy with concurrent and adjuvant temozolomide for newly diagnosed glioblastoma.

PURPOSE/OBJECTIVES: To assess the effect and toxicity of hypofractionated high-dose intensity modulated radiation therapy (IMRT) with concurrent and adjuvant temozolomide (TMZ) in 46 patients with newly diagnosed glioblastoma multiforme (GBM). METHODS AND MATERIALS: All patients underwent postsurgical hypofractionated high-dose IMRT. Three layered planning target volumes (PTVs) were contoured. PTV1 was the surgical cavity and residual tumor on T1-weighted magnetic resonance images with 5-mm margins, PTV2 was the area with 15-mm margins surrounding the PTV1, and PTV3 was the high-intensity area on fluid-attenuated inversion recovery images. Irradiation was performed in 8 fractions at total doses of 68, 40, and 32 Gy for PTV1, PTV2, and PTV3, respectively. Concurrent TMZ was given at 75 mg/m(2)/day for 42 consecutive days. Adjuvant TMZ was given at 150 to 200 mg/m(2)/day for 5 days every 28 days. Overall and progression-free survivals were evaluated. RESULTS: No acute IMRT-related toxicity was observed. The dominant posttreatment failure pattern was dissemination. During a median follow-up time of 16.3 months (range, 4.3-80.8 months) for all patients and 23.7 months (range, 12.4-80.8 months) for living patients, the median overall survival was 20.0 months after treatment. Radiation necrosis was diagnosed in 20 patients and was observed not only in the high-dose field but also in the subventricular zone (SVZ). Necrosis in the SVZ was significantly correlated with prolonged survival (hazard ratio, 4.08; P=.007) but caused deterioration in the performance status of long-term survivors. CONCLUSIONS: Hypofractionated high-dose IMRT with concurrent and adjuvant TMZ altered the dominant failure pattern from localized to disseminated and prolonged the survival of patients with GBM. Necrosis in the SVZ was associated with better patient survival, but the benefit of radiation to this area remains controversial.

[Multidisciplinary therapy for 3 patients with lymph node recurrence after curative gastrectomy].

We report multidisciplinary treatment of 3 patients with lymph node recurrence after curative gastrectomy. Case 1: A 71- year-old woman had a history of distal gastrectomy with D2 lymphadenectomy for the treatment of advanced gastric cancer. Para-aortic lymph node metastasis was observed 36 months after surgery. Complete response( CR) was achieved after concurrent chemoradiotherapy with S-1 plus radiation. Case 2: A 51-year-old man had a history of total gastrectomy with D2 lymphadenectomy for the treatment of advanced gastric cancer. Right cervical lymph node metastasis was observed 48 months after surgery. CR was achieved after concurrent chemoradiotherapy with S-1 plus radiation. Case 3: A 68-year-old man had a history of distal gastrectomy with D2 lymphadenectomy followed by neoadjuvant chemotherapy for the treatment of advanced gastric cancer. CR was achieved after sequential treatment with irinotecan( CPT-11) plus cisplatin( CDDP), radiation, and 5-fluorouraci(l 5-FU) plus Leucovorin therapy for lymph node recurrence near the head of the pancreas. These cases suggest that the combination of systemic chemotherapy and local radiation therapy might be effective for the treatment of lymph node recurrence in patients with gastric cancer.
