A novel mesenchymal-associated transcriptomic signature for risk-stratification and therapeutic response prediction in colorectal cancer.

Risk stratification in Stage II and III colorectal cancer (CRC) patients is critical, as it allows patient selection for adjuvant chemotherapy. In view of the inadequacy of current clinicopathological features for risk-stratification, we undertook a systematic and comprehensive biomarker discovery effort to develop a risk-assessment signature in CRC patients. The biomarker discovery phase examined 853 CRC patients, and identified a gene signature for predicting recurrence-free survival (RFS). This signature was validated in a meta-analysis of 1212 patients from nine independent datasets, and its performance was compared against established prognostic signatures and consensus molecular subtypes (CMS). In addition, a risk-prediction model was trained (n = 142), and subsequently validated in an independent clinical cohort (n = 286). As a result, this mesenchymal-associated transcriptomic signature (MATS) identified high-risk CRC patients with poor RFS in the discovery (hazard ratio [HR]: 1.79), and nine validation cohorts (HR: 1.86). In multivariate analysis, MATS was the most significant predictor of RFS compared to established prognostic signatures and CMS subtypes. Intriguingly, MATS robustly identified CMS4-subtype in multiple CRC cohorts (AUC = 0.92-0.99). In the two clinical cohorts, MATS stratified low and high-risk groups with a 5-year RFS in the training (HR: 4.11) and validation cohorts (HR: 2.55), as well as predicted response to adjuvant therapy in Stage II and III CRC patients. We report a novel prognostic and predictive biomarker signature in CRC, which is superior to currently used approaches and have the potential for clinical translation in near future.

Transcriptomic expression profiling identifies ITGBL1, an epithelial to mesenchymal transition (EMT)-associated gene, is a promising recurrence prediction biomarker in colorectal cancer.

The current histopathological risk-stratification criteria in colorectal cancer (CRC) patients following a curative surgery remain inadequate. In this study, we undertook a systematic, genomewide, biomarker discovery approach to identify and validate key EMT-associated genes that may facilitate recurrence prediction in CRC. Genomewide RNA expression profiling results from two datasets (GSE17538; N = 173 and GSE41258; N = 307) were used for biomarker discovery. These results were independently validated in two, large, clinical cohorts (testing cohort; N = 201 and validation cohort; N = 468). We performed Gene Set Enrichment Analysis (GSEA) for understanding the function of the candidate markers, and evaluated their correlation with the mesenchymal CMS4 subtype. We identified integrin subunit beta like 1 (ITGBL1) as a promising candidate biomarker, and its high expression associated with poor overall survival (OS) in stage I-IV patients and relapse-free survival (RFS) in stage I-III patients. Subgroup validation in multiple independent patient cohorts confirmed these findings, and demonstrated that high ITGBL1 expression correlated with shorter RFS in stage II patients. We developed a RFS prediction model which robustly predicted RFS (the area under the receiver operating curve (AUROC): 0.74; hazard ratio (HR): 2.72) in CRC patients. ITGBL1 is a promising EMT-associated biomarker for recurrence prediction in CRC patients, which may contribute to improved risk-stratification in CRC.

Effectiveness of Wound-Edge Protectors for Preventing Surgical Site Infections after Open Surgery for Colorectal Disease: A Prospective Cohort Study with Two Parallel Study Groups.

BACKGROUND: Standard procedures to reduce the surgical site infection (SSI) rate after colorectal surgery have not been established. A prospective cohort study with 2 parallel study groups was performed to clarify the SSI rate after open surgery with and without a wound-edge protector (WEP) for colorectal disease. METHODS: A total of 102 patients who underwent elective open surgery for colorectal disease between October 2012 and August 2014 were randomly assigned to a WEP group and a WEP (-) group. The primary endpoint was the SSI rate in both groups. RESULTS: Fifty-one patients were assigned to the WEP group and 51 to the WEP (-) group. Two patients were excluded from this study. The rate of SSI with and without a WEP was 16 and 36% respectively (p = 0.021). Older age (p = 0.0073) and no WEP (p = 0.021) were risk factors for SSI after open surgery for colorectal diseases on univariate analysis. On multivariate analysis, both older age (p = 0.016) and no WEP (p = 0.012) were independent risk factors for SSI. CONCLUSION: The present randomized, phase II trial found an SSI rate of 16% with use of a WEP. The SSI rate was lower in the WEP group than in the WEP (-) group. A WEP may reduce the SSI rate after open surgery for colorectal disease in Japanese patients.

mFOLFOX6 plus bevacizumab to treat liver-only metastases of colorectal cancer that are unsuitable for upfront resection (TRICC0808): a multicenter phase II trial comprising the final analysis for survival.

BACKGROUND: The TRICC0808 trial is a phase II multi-institutional trial that investigated the efficacy of preoperative mFOLFOX6 + bevacizumab (BV) therapy for liver-only metastasis that is unsuitable for upfront resection. The R0 resection rate in the efficacy analysis has been reported to be 44.4%, and the final analysis for survival was conducted (data fixation on February 16, 2015). METHODS: Six cycles of mFOLFOX6 + BV therapy were applied to patients with liver-only metastases, which were > 5 cm in diameter or more than four tumors (H2 and H3), and hepatectomy was performed if possible. Primary and secondary endpoints were the R0 hepatectomy rate and overall survival (OS), respectively. RESULTS: Of 46 patients registered, OS was analyzed for 45 patients in whom the 3-year OS rate from the starting date of chemotherapy was 44.0% with a 33.6-month median survival time (MST). The 3-year OS rate of 31 patients with hepatectomy, including resection after an additional chemotherapy, was 61.3% with a 43.1-month MST, which was significantly better than 0% of the 3-year OS rate with a 21.0-month MST of 14 patients without hepatectomy (p value < 0.0001). In 24 patients who underwent hepatectomy after six cycles of protocol chemotherapy, the 3-year relapse-free survival rate was 8.3%, with a 36.8-month MST. CONCLUSIONS: This final analysis of the TRICC0808 trial revealed a better long-term survival in patients with hepatectomy after mFOLFOX6 + BV therapy, although most examined patients eventually developed recurrence. Thus, hepatectomy after chemotherapy might improve the survival in patients with advanced liver metastases, although cure remains difficult.

Colorectal carcinoma: Ex vivo evaluation using q-space imaging; Correlation with histopathologic findings.

BACKGROUND: Although the prognosis of colorectal carcinoma (CRC) patients depends on the histologic grade (HG) and lymph node metastasis (LNM), accurate preoperative assessment of these prognostic factors is often difficult. PURPOSE: To assess the HG and extent of LNM by q-space imaging (QSI) for preoperative diagnosis of CRC. STUDY TYPE: Prospective. SPECIMEN: A total of 20 colorectal tissue samples containing adenocarcinomas and resected lymph nodes (LNs). FIELD STRENGTH/SEQUENCE: QSI was performed with a 3T MRI system using a diffusion-weighted echo-planar imaging sequence: repetition time, 10,000 msec; echo time, 216 or 210 msec; field of view, 113 × 73.45 mm; matrix, 120 × 78; section thickness, 4 mm; and 11 b values ranging from 0 to 9000 s/mm2 . ASSESSMENT: The mean displacement (MDP; µm), zero-displacement probability (ZDP; arbitrary unit [a.u.]), kurtosis (K; a.u.), and apparent diffusion coefficient (ADC) were analyzed by two observers and compared with histopathologic findings. STATISTICAL TESTS: Spearman's rank correlation coefficient, Mann-Whitney U-test, and ROC curve analyses. RESULTS: For all 20 carcinomas, the MDP, ZDP, K, and ADC were 8.87 ± 0.37 µm, 82.0 ± 6.2 a.u., 74.3 ± 3.0 a.u., and 0.219 ± 0.040 × 10-3 mm2 /s, respectively. The MDP (r = -0.768; P < 0.001), ZDP (r = 0.768; P < 0.001), and K (r = 0.785; P < 0.001) were significantly correlated with the HG of CRC, but not the ADC (r = 0.088; P = 0.712). There were also significant differences in the MDP, ZDP, and K between metastatic and nonmetastatic LNs (all, P < 0.001), but not the ADC (P = 0.082). In the HG of CRC and LNM, the area under the curve was significantly greater for MDP, ZDP, and K than for ADC. DATA CONCLUSION: QSI provides useful diagnostic information to assess the HG and extent of LNM in CRC. LEVEL OF EVIDENCE: 1 Technical Efficacy: Stage 2 J. Magn. Reson. Imaging 2018;48:1059-1068.

[Two Cases of Rectal Cancer with Pelvic Local Recurrence Complicated with Sepsis after Rectal Cancer Surgery Successfully Treated with Radiation Therapy].

Treatment of rectal cancer with postoperative pelvic recurrence may complicate infection and may be difficult to treat. We experienced 2 cases complicated with sepsis due to infection in the pelvic local recurrence in which radiation therapy was performed and they were shifted to outpatient molecular-targeted drug therapy. Case 1 involved a 58-year-old woman. In December 2011, colostomy and chemotherapy were performed for locally advanced rectal cancer. In June 2012, we performed low anterior resection. In January 2014, chemotherapy was started for pelvic recurrence. She discontinued treatment for 4 months due to personal circumstances. Recurrence was worsened, and infection caused sepsis and she was admitted to the hospital in February 2017. Infection was not improved with antibiotic drugs, and radiation therapy(60 Gy/30 times)was performed. Infection was improved, and panitumumab monotherapy was started and she was discharged. Case 2 involved a 61-year-old man. In February 2014, a lower anterior resection for rectal cancer was performed. In September 2015, chemotherapy was started for pelvic recurrence. In November 2016, chemotherapy was discontinued due to esophageal variceal rupture. Recurrence was worsened, and infection caused sepsis and he was admitted to the hospital in May 2017. Radiation therapy(50 Gy/20 times)was performed after colostomy. Infection was improved, and cetuximab monotherapy was started and he was discharged.

Morphologic change of the psoas muscle as a surrogate marker of sarcopenia and predictor of complications after colorectal cancer surgery.

PURPOSE: Sarcopenia is reported to be associated with complications after surgery. However, there is no established optimal parameter to determine sarcopenia affecting surgical outcome. This study investigated whether morphologic change of the psoas muscle (MPM) reflects sarcopenia and could be a predictor of complications after colorectal cancer surgery. METHODS: Colorectal cancer patients who underwent primary tumor resection with anastomosis between 2015 and 2016 were analyzed. MPM score was evaluated as the ratio of the short-to-long axis of the psoas muscle in CT images at the L3 vertebrae and classified into five MPM grades. Then, the impact of MPM grade on development of postoperative complications was investigated. RESULTS: A total of 133 patients were studied. MPM score was significantly correlated to the sectional areas of the psoas muscle at the L3 vertebrae which was evaluated by manual tracing. 21.1% of the subjects were classified into severe MPM (defined as MPM grade 3-4). Overall and infectious complications were noted in 37 (27.8%) and 16 (12.0%) patients. Severe MPM (odds ratio [OR] 2.71, 95% confidence interval [CI] 1.09-6.73), longer operative time (OR 1.01, 95%CI 1.001-1.01), and open surgery (OR 2.73, 95%CI 1.17-6.35) were identified as independent risk factors of overall complications. Severe MPM (OR 4.26,95%CI 1.38-13.10) and open surgery (OR 3.42, 95%CI 1.11-10.48) were identified as independent factors associated with infectious complications. CONCLUSIONS: MPM grade may be used as a simple and convenient marker of sarcopenia and to identify patients at increased risk of complications after colorectal cancer surgery.

[Long-Term Survival of a Case with Brain and Lung Metastases from Resected Rectal Cancer by Gamma Knife Radiosurgery].

A 69-year-oldfemale hadund ergone low anterior resection for rectal cancer(Rb). Histological examination showedwell differentiated adenocarcinoma with lymph node metastasis. Adjuvant chemotherapy with UFT was performed postoperatively. Nineteen months later, abdominoperineal resection was performedfor anastomotic recurrence andS -1 chemotherapy was made. As 2 left lung metastases appearedat the 44 months after first surgery, capecitabine was performedfor 4 years. At the 101 months after first surgery, sensory difficulty of right lower limb appearedandMRI revealedbrain tumor(single, 18mm) in the left parietal lobe. We performedgamma knife radiosurgery for the brain metastasis andmultiagent chemotherapy for lung metastases. Although the brain metastases have relapsedtwice, gamma knife providedgoodlocal control. She is surviving without symptom of brain metastases 37 months after the detection.

[Two Cases of Colon Cancer with Severe Liver Dysfunction Due to Multiple Liver Metastases Effectively Treated with Hepatic Arterial Infusion Chemotherapy plus CetuximabFollowed by Systemic Chemotherapy].

Case 1: An 80-year-old man was diagnosed with cecal cancer plus multiple liver metastases and peritoneal disseminations. He underwent surgical resection of the primary tumor to prevent bowel obstruction. Initially, hepatic arterial infusion(HAI) plus cetuximab(Cmab)was administered to reduce the size of the metastatic tumors and prevent liver failure. A partial response(PR)was observed in the liver metastases after 12 courses of treatment and S-1 plus oxaliplatin(SOX)plus bevacizumab was started. Case 2: A 44-year-old man was diagnosed with sigmoid colon cancer with multiple liver, lung and bone metastases, and with obstructive jaundice and cholangitis due to severe liver hilum lymph node metastases. His performance status(PS)score was 3 because of severe liver damage. Initially, he underwent endoscopic nasobiliary drainage for obstructive jaundice, and HAI plus Cmab was started to prevent liver dysfunction and to control all metastases. A PR in the metastatic liver tumors was observed after 18 courses. His PS increased to 1 and he was treated with mFOLFOX6 plus Cmab. HAI plus Cmab might be a treatment option for patients who have RAS-wild type tumors with severe liver dysfunction due to multiple liver metastases; HAI is intended to have few side effects and has a high local control rate.

[A Case of Metastasis to the Base of the Skull after Rectal Cancer Operation with Symptom Management via Radiotherapy].

In 2009, A 67-year-old woman underwent high anterior resection for rectal cancer(RS, type 2, pT3, pN1, cM0, pStage III a). U FT/LV was administered for 6 months as adjuvant chemotherapy after the operation. Because peritoneum dissemination and pelvic lymph node metastasis developed 9 months after the operation, CapeOX plus Bmab therapy was started, and we monitored the cancer partial response for the next 6 years. Six years and 9 months after the operation, we detected metastasis to the sacrum; thus, radiotherapy was started. Seven years after the first operation, we detected pulmonary, liver, distant lymph node, and subcutaneous metastasis. Additionally, in the next month, she complained of double vision and dysarthria, and metastasis to the base of the skull was diagnosed via head MRI scanning. We started radiotherapy, and the symptoms gradually improved. Although we started IRIS plus Bmab therapy for pulmonary, liver, distant lymph node, and subcutaneous metastasis, it became a progressive disease(PD). She passed away 7 years and 6 months after the first operation. In this case, radiotherapy was useful for symptom management of metastasis to the base of the skull after surgery for rectal cancer, which is an extremely rare occurrence.

[Adjuvant Chemotherapy for Colorectal Cancer].

The purpose of adjuvant chemotherapy for patients with colorectal cancer treated with curative surgery is to prevent from metachronous recurrences and to improve their prognosis. Because surgical outcomes in Japan are relatively better compared to those in western countries, optimal and personalized treatment based on evidence introduced not only by other countries but by Japan should be chosen. We now focus on a research of identification of biomarker which predict high risk of recurrence in Stage II colorectal cancer.

[A Rare Case of Retroperitoneal Metastasis from Ascending Colon Cancer That Required Multimodal Treatment].

A patient in his 70's underwent a right hemi-colectomy due to an ascending colon cancer in a previous hospital. The tumor had widely infiltrated the retroperitoneal space(pT3, pN0[0/12], pPM0, pDM0, pRM1, Stage II ). He was referred to our institute 1 month after primary surgery to receive chemotherapy for his residual tumor. Abdominal computed tomography (CT)showed a 24mm tumor in his retroperitoneal space before chemotherapy. After 4 cycles of mFOLFOX6 and panitumumab, the tumor partially responded, and after 7 cycles, he achieved a complete response(CR). After an additional 10 cycles, he had maintained the CR, and chemotherapy was discontinued. Two years and 11 months after discontinuation of chemotherapy, an abdominal CT revealed a tumor that gradually grew behind the right kidney. The tumor was resected, and pathological findings showed it was recurrence of the past colon cancer. Seven months after resection of recurrent tumor, CT revealed 2 newly recurrent tumors that gradually grew in the retroperitoneal space again. Therefore, we performed resection of newly recurrent tumors along with the right kidney, Gerota's fascia, diaphragm, and lumbar quadrate muscle for R0 resection. Pathological findings revealed recurrence of the past colon cancer with extensive lymphatic invasion. The recurrent tumor had grown in a retroperitoneal space that was not covered in the primary surgical procedure. Therefore, this is considered a rare case of retroperitoneal metastasis.

A multicenter phase II trial of mFOLFOX6 plus bevacizumab to treat liver-only metastases of colorectal cancer that are unsuitable for upfront resection (TRICC0808).

BACKGROUND: A phase II clinical trial was conducted on colorectal cancer patients with only liver metastases (focal diameter exceeds 5 cm or the number of liver metastases is ≥5; H2·H3) to evaluate the liver resection rate and safety after 6 cycles of mFOLFOX6+bevacizumab (BV) therapy. METHODS: mFOLFOX6+BV therapy was applied for 6 cycles to the patients with H2·H3 liver only metastasis. Hepatectomy was considered after the sixth cycle as a rule, and was performed if possible. The primary endpoint was the curative hepatectomy rate (R0 resection rate). RESULTS: Forty-six patients were registered and 45 patients were included in the efficacy analysis. Of the 19 patients rated as unresectable before therapy, 18 completed 6 cycles of mFOLFOX6+BV therapy and subsequently underwent hepatectomy (16 were R0-resected). Of the 26 initially unresectable patients, 6 underwent hepatectomy (4 were RO-resected). The overall R0 resection rate was 44.4% (20/45). Chemotherapy-associated grade 3 or higher adverse events included neutrophil decreased (17.4%) and leukocyte decreased (8.7%), fatigue (6.5%) etc. Only hypertension (6.5%) and venous thromboembolism (2.2%) were BV-associated grade 3 or higher adverse events. Among the 25 patients who underwent hepatectomy, intraoperative/postoperative complications included grade 3 wound infections (2 cases), biloma, delayed wound healing and intraperitoneal abscess (each 1 case). CONCLUSIONS: In colorectal cancer patients with liver-only metastases, mFOLFOX6+ BV therapy yielded a high hepatectomy rate and a high percentage of initially unresectable and subsequently resectable cases. The chemotherapy associated adverse events and hepatectomy complications were both within acceptable ranges.

Validation and Modification of the Japanese Classification System for Liver Metastases from Colorectal Cancer: A Multi-institutional Study.

BACKGROUND: A Japanese multicenter study disclosed four prognostic indicators of colorectal cancer liver metastases: ≥5 hepatic tumors (HT), HT size > 5 cm, nodal status (N2) of primary cancer, and the presence of extrahepatic metastases (EM). The Japanese classification was then defined as Stage A, HT1 (≤4 lesions and ≤5 cm) and N0/1; Stage B, HT2 (≥5 lesions or >5 cm) and N0/1, or HT1 and N2; and Stage C, HT2 and N2, HT3 (≥5 lesions and >5 cm) with any N, or EM1 (presence of EM) with any HT/N. This study aimed to validate the prognostic reliability in a recent population and to develop a modified staging system that divided Stage C patients. METHODS: A total of 1185 patients diagnosed with liver metastases between 2007 and 2008 were enrolled in the study. According to the classification, 358, 257, and 570 patients were categorized as Stages A, B, and C, respectively. Stage C was further divided into two groups: Stage C-I, HT3 and N0/1, HT2 and N2, or HT1 and EM1; and Stage C-II, HT3 and N2, or HT2/3 and EM1. RESULTS: Cumulative overall survival curves for Stages A, B, and C were significantly different between each two stages (p < 0.0001, p < 0.0001). The modified system discriminated patients with a relatively better outcome (Stage C-I) from desperate patients (Stage C-II) (p < 0.0001). CONCLUSIONS: The Japanese classification system was adequately validated in a recent population, and the modified system is useful in risk stratification of Stage C cases.

Combined evaluation of the Glasgow prognostic score and carcinoembryonic antigen concentration prior to hepatectomy predicts postoperative outcomes in patients with liver metastasis from colorectal cancer.

BACKGROUND/AIMS: Little is known about the ability of the inflammation-based Glasgow prognostic score (GPS). METHODOLOGY: 106 patients who underwent curative resection for colorectal liver metastasis (CRLM) were analyzed. Patients with an elevated Creactive protein concentration (>10 mg/L) and hypoalbuminemia (<35 g/L) at admission were assigned a GPS 2, those with only 1 of these biochemical abnormalities were assigned a GPS 1, and those without either abnormality were assigned a GPS 0. RESULTS: Multivariate analysis showed that 2 variables, carcinoembryonic antigen (CEA) concentration > 30 ng/mL and a GPS 1 or 2, were independently prognostic of survival. Patients were classified into 3 groups on the basis of these 2 variables. Patients with GPS 1 or 2 and CEA concentration > 30 ng/mL were assigned a new score of 2, those with either 1 factor were assigned a new score of 1, and those with neither factors were assigned a new score of 0. The 5-year overall survival rates of new scores of 0, 1, 2 were 71.5%, 31.6%, and 0%, respectively (P < 0.0001). CONCLUSIONS: This simple staging system may be able to identify a subgroup of patients who are eligible for curative resection but show poor prognosis.

[Clinical analysis of delayed hemothorax due to diaphragmatic injury treated by emergent video-assisted thoracic surgery].

We encountered 5 cases of delayed massive hemothorax due to diaphragmatic injury. Delayed hemothorax presented 2∼11 days after injury, with lower rib fractures seen all cases. We performed emergent video-assisted thoracic surgery with mini-thoracotomy for all patients. Lacerations could be clearly visualized in the diaphragm after evacuation of blood clots, which were then sutured. In four cases, the sharp edges of the broken ribs were thought to have caused the diaphragmatic lacerations. The mean blood loss volume was 2,905 ml, and all patients required blood transfusions. However, homeostasis was achieved after surgery, and all patients had an uneventful postoperative course. Although, delayed hemothorax is relatively uncommon, it needs to be considered a lethal condition.

[Long-term survival following resection of primary rectal cancer metachronous metastases and salvage surgeries for relapsed lesions after stereotactic body radiotherapy for lung metastases - a case report].

A 66-year-old man underwent abdominoperineal resection for rectal cancer in 2003, followed by liver resection for a solitary liver metastasis in 2005. In 2006, the patient underwent abdominal para-aortic lymph node dissection, which was performed concurrently with partial resections of 3 metastases in the right lung. New metastatic lesions were subsequently diagnosed in S8 of the right lung and S1+2 of the left lung. The patient underwent stereotactic body radiotherapy (SBRT) for both lesions. However, the lesions relapsed and salvage surgeries were subsequently performed. These included a partial resection in 2009 for the lesion in the right lung and an upper division segmentectomy in 2010 for the lesion in the left lung. Currently, 11 years after resection of the primary rectal cancer, the patient is asymptomatic, without any signs of recurrence. In this report, we describe the use of SBRT for the treatment of colorectal cancer pulmonary metastases, and the use of salvage surgery for relapsed lesions.

[Rectal cancer with local re-recurrence successfully treated by carbon ion radiotherapy].

A 61 year-old male with rectal cancer underwent anterior resection with D2 lymph node dissection in August 2007. Carcinoembryonic antigen (CEA) level was 5.6 before the operation. Pathological findings were Rs, tub2¼>tub1, type 3, pSE, ly1, v2, pN1 (1/23), H0, P0, M0 , pStage IIIA. Adjuvant chemotherapy with tegafur-uracil (UFT) 600 mg/Leucovorin (LV) 75 mg was administered for 1 year. A recurrence at a site of anastomosis developed and lower anterior resection was required in September 2010. CEA level was 5.4 before the operation. After 7 courses of capecitabine plus oxaliplatin (XELOX) treatment, the right #283 lymph node increased to 8 mm in October 2011 and the patient was diagnosed with a re-recurrence of the original tumor (CEA level, 4.6). Carbon ion radiotherapy (73.6 Gy/16 Fr/4 weeks) was performed between November 28 and December 22, 2011. Although the right #283 lymph node had shrunk by January 2012, a single node in the S3 domain of the right lung was observed and became progressively larger, indicating a lung metastasis (CEA level, 5.4). The patient received carbon ion radiotherapy (60.0 Gy/4 Fr) for the lung metastasis between July 30 and August 2, 2012. No additional recurrences have been seen through February 2014.

[A successful treatment by surgery for axillary lymph node recurrence of lung cancer].

This case concerns a 78-year-old man, who was diagnosed with lung cancer at the age of 73. He underwent right lobectomy and lymph node dissection, and pathological analysis revealed a poorly differentiated adenocarcinoma, pT1N0M0 pStage IA. 15 months after surgery, computed tomography showed recurrence of lung cancer at the apex of thoracic cavity. He underwent radiation to the recurrence site, and 33 months after surgery, fluorodeoxyglucose uptake was observed at the axillary and infraclavicular lymph nodes in positron emission tomography examination. Treatment with pemetrexed was started because carcinomatous pericarditis was also found. Although pericardial effusion disappeared, the patient complained of the enlarged size of the axillary and infraclavicular lymph nodes and severe numbness in an arm. Beyond lymph node involvement, no other metastatic sites were found. An operation was performed to relieve the pain and the pathological analysis of lymph nodes showed metastases of lung cancer. The operation successfully reduced the pain experienced by the patient. There has been no further recurrence in the 9 months following surgery. Axillary lymph node metastasis is thought to be a distant metastasis; however, this is a case where local control was needed and was effective.
