Evaluation of Chemotherapy-induced Dysgeusia in Patients With Gastrointestinal Cancer: A Pilot Study.

BACKGROUND/AIM: Dysgeusia, one of the adverse effects of cancer chemotherapy, and anorexia due to taste disorder can significantly impair the quality of life of patients. However, an evaluation method for dysgeusia has not yet been established. The present prospective study aimed to utilize a combination of subjective and objective assessment methods to evaluate dysgeusia in patients with gastrointestinal cancer initiating chemotherapy, to determine chemotherapeutic drugs and regimens causing dysgeusia, and to assess whether dysgeusia was associated with zinc deficiency. PATIENTS AND METHODS: A total of 21 patients with newly diagnosed gastrointestinal cancer were registered between August 2020 to March 2021. The following regimens were also included in the evaluation if the patients did not develop dysgeusia. A total 30 regimens were administered to the patients during the study period. A salt-impregnated test paper (Salsave®) was used as a subjective assessment, and the chemotherapy-induced taste alteration scale was used as an objective assessment. RESULTS: Based on physician interviews, dysgeusia was diagnosed in 8 of 21 patients (38%) treated with 8 of 30 regimens (27%). All regimens that resulted in dysgeusia contained platinum-based drugs. The patients who developed dysgeusia had higher controlling nutritional status scores at the start of chemotherapy compared to those who did not develop dysgeusia. In both subjective and objective assessments, the patients with dysgeusia performed significantly worse than those without dysgeusia. Six of the eight patients who developed dysgeusia were administered Novelzine, which did not improve the taste disorder despite the improvement of serum zinc levels. CONCLUSION: The combined approach using subjective and objective taste assessment methods was useful in assessing chemotherapy-induced dysgeusia. Mechanisms other than hypozincemia should be considered as contributors to taste disorders caused by platinum-based drugs.

Nonfixation of mesh in laparoscopic totally extraperitoneal inguinal hernia repair: A propensity score matched analysis.

BACKGROUND: Regarding the need for mesh fixation in total extraperitoneal inguinal hernia repair (TEP), several studies have found no significant differences in the recurrence rate between patients with and without fixation. Furthermore, there is no report on the outcome of this treatment from Japan. We aimed to analyze the outcomes of nonfixation TEP with those of fixation at our institute. METHODS: In May 2016, the nonfixation TEP technique was launched. The fixation group (165 patients) was compared to the nonfixation group (195 patients). Because of the significant bias between the two groups, a propensity score matched analysis was performed (with 109 patients in each group). Moreover, only ordinary cases (with 58 patients in each group) were compared, excluding bilateral, large, and impaction cases. RESULTS: One patient in the nonfixation group experienced recurrence. It was a hernia case with a large orifice. In the fixation group, seroma was more prevalent; however, no differences were observed between the two groups in propensity score matching. In unilateral cases, the nonfixation group had a shorter operation time and stayed in the hospital for a shorter time postoperatively. The ordinary cases, excluding cases of bilateral hernias, large hernias on visual examination, impactions, and large hernial orifices, showed no recurrence or significance in surgical complications. CONCLUSIONS: The nonfixation TEP was considered acceptable at least for ordinary hernial cases.

Prognostic Nutritional Index Considering Resection Range Is Useful for Predicting Postoperative Morbidity of Hepatectomy.

BACKGROUND: Poor preoperative nutritional and immunological status are major risk factors for postoperative complications in patients with various malignancies. Lower preoperative prognostic nutrition index (PNI) is associated with higher rates of postoperative complications and poorer prognosis in those patients. The aim of this study was to analyze the predictive value of the PNI for post-hepatectomy complications in patients with hepatocellular carcinoma (HCC), and evaluate its utility in the surgical procedure. METHODS: This retrospective study included 510 patients who underwent open hepatectomies for HCC. The predictive value of the preoperative nutritional and immunological status for postoperative complications was assessed using the PNI. Postoperative complications were defined as grade II or higher per the Clavien-Dindo classification. Postoperative complication rates were compared according to surgical procedure (major hepatectomy vs minor hepatectomy). RESULTS: Patients with postoperative complications had significantly lower PNIs than those without (43.1 ± 5.5 vs 47.0 ± 5.7, P < 0.001). In the multivariate analysis, low preoperative PNI (< 45) was an independent risk factor for postoperative complications after hepatectomy (hazard ratio, 3.85). When patients were classified per their PNI (high vs low) and extent of surgical procedures (major vs minor), there were more complications among patients with low PNI than those with high PNI, regardless of the extent of surgical procedures. Specifically, the group of patients with low PNI who underwent major hepatectomy had significantly higher rates of postoperative complications than the other groups. CONCLUSIONS: Adding the resection range to the PNI is useful for predicting the postoperative morbidities of hepatectomy patients.

Extended total gastrectomy after nivolumab for unresectable multivisceral invasive gastric cancer.

BACKGROUND: Chemotherapy has been considered the main treatment for stage IV gastric cancer (GC). However, advances in chemotherapy have provided new clinical approaches, permitting conversion surgery with the aim of R0 resection after resolving unresectability issues. CASE PRESENTATION: A 70-year-old man with gastric cancer invading the pancreatic tail and spleen and with periaortic lymph-node enlargement was admitted to our hospital. After 24 courses of nivolumab as third-line chemotherapy, periaortic lymph-node enlargement was resolved, and conversion surgery was planned. Intraoperatively, we found no peritoneal metastasis, but the distal pancreas, splenic hilum, and transverse colon were adhered to the gastric body. Therefore, we performed D2 total gastrectomy with distal pancreatosplenectomy and partial transverse colectomy. The pathological diagnosis was type III moderately differentiated tubular adenocarcinoma (tub2) with signet ring cells, stage ypT1b (SM), ly0, and v0. The pathological proximal and distal tumor margins were negative. One lymph-node metastasis was observed (No. 4d; 1/23). Postoperatively, no recurrence was observed over 7 months, without adjuvant chemotherapy. CONCLUSIONS: Nivolumab may allow R0 resection in patients with unresectable gastric cancer. Conversion surgery should be considered even after third-line nivolumab treatment.

Successful Conversion Surgery Following Chylous Ascites After Nivolumab for Advanced Gastric Cancer.

CASE REPORT: A 75-year-old man who underwent nivolumab as the third-line chemotherapy for advanced gastric cancer had chylous ascites (CA) after the primary tumor shrank remarkably. Total parenteral nutrition and subcutaneous octreotide were initiated, and CA disappeared. Nivolumab was continued for a total of 23 courses. Computed tomography showed lymph node swelling; however, staging laparoscopy showed that peritoneal metastasis had disappeared. Therefore, conversion surgery and distal gastrectomy with D1+ dissection were performed. RESULTS: The pathological diagnosis was type IV, poorly differentiated adenocarcinoma (por2) with signet ring cells, ypT2 (muscularis propria), without lymphatic or venous invasion, and no involvement of the proximal and distal margins. After the operation, no recurrence was observed over 7 months with no adjuvant chemotherapy. CONCLUSION: Nivolumab has the potential to lead to R0 resection for patients with peritoneal carcinomatosis gastric cancer. To our knowledge, this is the first report of successful conversion surgery after nivolumab-related chylous ascites.

Mesenteric venous thrombosis as a rare complication of decompression sickness.

BACKGROUND: Decompression sickness (DCS) induced by extravascular and intravascular gas bubbles during decompression can present with varying manifestations, such as joint pain, numbness, cutaneous symptoms, and cardiopulmonary dysfunction. However, mesenteric venous thrombosis (MVT) is a rare complication of DCS. To the best of our knowledge, only a few cases have been reported, and surgical cases of MVT secondary to DCS have not yet been reported. CASE PRESENTATION: A 59-year-old man who was a fisherman and recreational diver dived to a depth of 100 feet. After diving, he noted abdominal and postcervical pain and visited a community hospital. Computed tomography (CT) revealed a large amount of intravenous gas, so he was diagnosed with DCS. He was then transferred to a previous hospital, where hyperbaric oxygen therapy (HBOT) was performed. HBOT reduced the amount of venous gas, but his abdominal pain worsened, so he was transferred to our hospital. CT showed pneumatosis cystoides intestinalis. Because of the possibility of intestinal necrosis, a laparoscopic examination was performed, which revealed necrosis of the transverse colon. We therefore performed a transverse colon resection. He was discharged 36 days after the surgery and followed an uneventful postoperative course. CONCLUSIONS: DCS is likely to cause MVT. If intestinal necrosis is suspected, a laparoscopic examination may be useful for determining the diagnosis and treatment. MVT should be included as a differential diagnosis of abdominal pain that persists after HBOT.

Post-hepatectomy Refractory Ascites in Cirrhotic Patients with Hepatocellular Carcinoma: Risk Factor Analysis to Overcome this Problematic Complication.

BACKGROUND: Refractory ascites is a serious post-hepatectomy complication in cirrhotic patients with hepatocellular carcinoma (HCC). In order to avoid this complication, surgeons should preserve as much liver parenchyma as possible in performing hepatectomy in such patients. However, we still occasionally encounter refractory ascites even after limited or small hepatectomy. The aim of this study was to identify risk factors for post-hepatectomy refractory ascites in cirrhotic patients, focusing on limited or small hepatectomy. PATIENTS AND METHODS: The data of 73 cirrhotic patients with HCC who underwent limited or small hepatectomy were analyzed. Limited or small hepatectomy was defined as hepatectomy equal to or of less than subsegmentectomy. We compared the clinicopathological factors between patients with and without postoperative refractory ascites. RESULTS: Fourteen cirrhotic patients suffered postoperative refractory ascites. Total cholesterol, duration of operation, duration of Pringle maneuver, resection of segment VII, intraoperative blood loss, and intraoperative blood transfusion were found to be significant risk factors for postoperative refractory ascites in univariate analyses. Multivariate analysis revealed that resection of segment VII was an independent risk factor. CONCLUSION: Resection of segment VII necessitates extensive dissection of the right triangular or coronary ligaments, which could explain that it was an independent risk factor for post-hepatectomy refractory ascites. Surgeons should avoid extensive dissection of these ligaments in order to avoid this detrimental complication.

Characteristic risk factors in cirrhotic patients for posthepatectomy complications: comparison with noncirrhotic patients.

There seemed to be characteristic risk factors in cirrhotic patients for posthepatectomy complications because these patients have less hepatic reserve as compared with noncirrhotic patients. The aim of the current study was to identify these characteristic risk factors in cirrhotic patients. We performed 419 primary hepatectomies for hepatocellular carcinoma. The patients were divided into the cirrhotic group (n = 198) and the noncirrhotic group (n = 221), and the risk factors for posthepatectomy complications were compared between the groups. Thirty-six cirrhotic patients (18.2%) experienced Clavien's Grade III or more complications. Tumor size, intraoperative blood loss, duration of operation, major hepatectomy (two or more segments), and necessity of blood transfusion were found to be significant risk factors in univariate analyses. Multivariate analysis revealed that major hepatectomy and intraoperative blood loss were independent risk factors for posthepatectomy complications in patients with cirrhosis. On the other hand, the duration of operation was only an independent risk factor for posthepatectomy complication in noncirrhotic patients. Cirrhotic patients should avoid a major hepatectomy and undergo a limited resection preserving as much liver tissue as possible and meticulous surgical procedures to lessen intraoperative blood loss are mandatory to prevent major posthepatectomy complications.

Outcomes of emergency surgery for acute abdomen in dialysis patients: experience of a single community hospital.

PURPOSE: Long-term dialysis often causes physiological and metabolic problems that may affect the outcomes of surgery. The aim of this study was to elucidate whether emergency surgery for acute abdomen yields similar outcomes in dialysis patients versus non-dialysis patients. METHODS: The subjects were 126 patients who underwent emergency surgery for acute abdomen between January, 2007 and November, 2011 in our hospital. They were divided into a dialysis group (HD group; n = 9) and a non-dialysis group (non-HD group; n = 117) and their postoperative morbidity and mortality were compared. RESULTS: Postoperative morbidity and mortality were significantly worse in the HD group. All 9 of these patients succumbed to postoperative complications versus only 5 of the 117 patients in the non-HD group. CONCLUSION: The outcomes of emergency surgery for acute abdomen were significantly worse for dialysis patients than for non-dialysis patients. Prompt diagnosis, initiation of the most suitable surgical procedure, and meticulous postoperative cares are imperative to improving the surgical outcomes of dialysis patients.

Nasal MRSA screening for surgical patients: predictive value for postoperative infections caused by MRSA.

PURPOSE: Postoperative methicillin-resistant Staphylococcus aureus (MRSA) infections are occasionally fatal. We hypothesized that nasal MRSA screening might predict the risk of postoperative MRSA infections. The aim of the current study was to elucidate the relationship between the positivity of nasal MRSA screening and postoperative MRSA infections. METHODS: Six hundred and fourteen surgical patients who were admitted to the intensive care unit and underwent nasal MRSA screening between April 2006 and March 2011 were divided into MRSA-positive and -negative groups. The incidence of postoperative MRSA infections in the MRSA-positive and MRSA-negative groups were compared, and various risk factors for MRSA infections were evaluated. RESULTS: The incidence of postoperative MRSA infections, such as pneumonia and enteritis, in the MRSA-positive group was significantly higher than that in the MRSA-negative group (41.9 vs. 3.1 %). The significant independent risk factors for postoperative MRSA infections were a positive MRSA screening, an operation lasting more than 300 min and an emergency operation. A positive MRSA screening was the most statistically significant risk factor for postoperative MRSA pneumonia and enteritis, but was not a risk factor for MRSA surgical site infections. CONCLUSION: Nasal MRSA screening can help to identify patients who have an increased risk of developing postoperative MRSA infections, and would enable physicians to take a prompt action if these complications occur.

High energy trauma patients treated in the department of general surgery in a secondary emergency facility in Japan.

OBJECTIVE: We clarified the characteristics of the high energy trauma patients that entered the general surgery ward of Fukuoka city hospital (FCH), a 200 bed secondary emergency hospital in Japan. PATIENTS AND METHODS: Of the 7,826 total ambulance cases treated from April 2008 to March 2012 in our emergency room, 831 trauma patients who entered our hospital were analyzed. These patients were classified into a non high energy (NHE) and high energy trauma (HE) group based on the mechanisms of injuries. RESULTS: Of the 831 trauma cases, 741 (89.2%) were in the NHE and 90 (10.8%) were in the HE group. Eleven of the 741 cases (1.5%) in the NHE group and 18 of the 90 cases (20.0%) in the HE group entered the Department of General Surgery as inpatients, with the frequency being significantly higher in the latter group (p < 0.01). 11 of the 18 cases (61.1%) of Department of General Surgery in the HE group were diagnosed to have an injury severity score (ISS) of 15 or higher, and the rate of preventable trauma deaths (PTDs) of those 11 cases was 9.1% (1/11). CONCLUSIONS: The proportion of the patients that entered the Department of General Surgery was higher in the HE group than in the NHE group. The surgical departments of secondary emergency facilities are expected to contribute to the local trauma emergency systems.

Pure laparoscopic partial hepatectomy using a newly developed vessel sealing device, BiClamp.

PURPOSE: The aim of the current study was to investigate whether pure laparoscopic partial hepatectomy can be safely performed using a newly developed vessel sealing device, BiClamp. METHODS: Nine cases of pure laparoscopic partial hepatectomy were performed by simply transecting liver parenchyma using the BiClamp. Four patients had a cirrhotic liver. The median tumor diameter was 1.5 cm (range, 1.0 to 2.7 cm). The tumors were located in segment (S) 3 in 3 cases, S4 in 1 case, S5 in 2 cases, S6 in 1 case, and S8 in 2 cases. Simultaneous cholecystectomy was performed in 4 cases. RESULTS: The median operation time was 187 minutes (range, 83 to 423 min) and the median estimated blood loss was little (range, little to 417 mL). All patients were discharged from the hospital without any adverse postoperative consequences. CONCLUSIONS: BiClamp is an effective device for transecting liver parenchyma during pure laparoscopic partial hepatectomy, even in cirrhotic livers.

Results of laparoscopic gastrectomy for early gastric cancer in high-risk patients - estimation of surgical risk of gastrectomy.

BACKGROUND/AIMS: Surgical risk of laparoscopic gastrectomy for gastric cancer in high risk patients was evaluated with E-PASS scoring system. METHODOLOGY: This study was based on 63 patients with gastric cancer who underwent laparoscopic gastrectomy; 14 patients belonging to high risk group (ASA≥3) and 49 classified as low risk group (ASA≤2). Fifty six patients who underwent conventional gastrectomy were used for comparison. RESULTS: Intra- and postoperative complications were found in 4 and 3 of 14 high risk patients, respectively. We found a significant correlation between E-PASS score and complications. E-PASS score in high risk group was significantly higher than the value in low risk group. The estimated in-hospital mortality rate was significantly different between the two groups. When conventional gastrectomy group for high risk patients was compared, postoperative morbidity and mortality rates were similar in two surgical procedures; however E-PASS score and the estimated in-hospital mortality rate with conventional gastrectomy were significantly higher than the value with laparoscopic gastrectomy. CONCLUSIONS: There were no fatal complications in high risk patients with laparoscopic gastrectomy and E-PASS score was within safety margin. Extension of laparoscopic surgery in high risk patients was feasible when careful procedure was performed by a surgical team.

Significant prognostic factors in patients with Stage IV gastric cancer with special reference to the curability of surgery.

PURPOSES: The purpose of this study was to determine an effective treatment strategy for patients with Stage IV gastric cancer. METHODS: We analyzed the significant prognostic factors in 74 patients who underwent surgery between 1989 and 2005, and were finally determined to have Stage IV gastric cancer. These patients were classified as curability A (n = 0), B (n = 29) and C (n = 45) according to the criteria outlined by Japanese Gastric cancer society. Anti-tumor drugs were used after surgery in some cases. There were 32 patients who received either no treatment or an oral anti-tumor drug, and 42 patients who received new chemotherapeutic regimens. RESULTS: According to a univariate analysis, the postoperative mean survival times were significantly different; tumor size ≤ 12 cm, a tumor without lymphatic involvement, more than D2 lymphadenectomy, and classification as curability B were favorable prognostic factors. The multivariate analysis revealed that tumor size, lymphadenectomy and curability were independent prognostic factors. In curability B patients, venous involvement was an independent prognostic factor. In curability C patients, both the tumor size and postoperative chemotherapy affected their prognosis. CONCLUSIONS: In patients with curable Stage IV gastric cancer, at least a D2 gastrectomy to reduce the absolute volume of tumor cells, followed by adjuvant chemotherapy, may be essential to improve their prognosis. In incurable cases, aggressive new chemotherapeutic regimens should be the treatment of choice for the prolongation of survival.

Ten-year survival of curability B gastric cancer patients treated by tegafur-uracil as postoperative adjuvant chemotherapy in a common public hospital: univariate and multivariate analyses.

PURPOSE: The prognosis of gastric cancer patients undergoing curability B surgery was retrospectively examined to determine the effectiveness of the administration of oral anti-cancer drugs as postoperative adjuvant chemotherapy. METHODS: This study was based on the outcomes of 86 potentially curative patients who had undergone curability B resection of gastric cancer with or without the subsequent administration of oral 5-fluorouracil analogue. There were 21 patients who underwent surgery alone with no oral anti-cancer agents (group A) and 65 patients who were treated postoperatively, mainly with UFT (Tegafur and uracil; group B). This study compared the ten-year survival times of these two groups using univariate and multivariate analyses. RESULTS: The amount of UFT in group B was 354.2 +/- 122.0 mg and the administration period was 11.7 +/- 7.2 months. The backgrounds showed significantly more older patients in group A compared than group B (P = 0.0002). A univariate analysis showed the ten-year survival rate in group B to be higher than group A (P = 0.0079). A multivariate analysis showed that the postoperative administration of UFT was an independent factor associated with prolongation of survival times as well as the extent of lymph nodes metastasis and pathological stage (P = 0.0096). CONCLUSION: This study provided conventional evidence that postoperative administration of oral 5-fluorouracil analogue is associated with better long-term prognoses in patients undergoing curability B resection for gastric carcinoma.

The effect of overweight status on the short-term and 20-y outcomes after hepatic resection in patients with hepatocellular carcinoma.

BACKGROUND: We aimed to evaluate the impact of body mass index (BMI) on the short- and long-term outcomes of hepatic resection in patients with hepatocellular carcinoma (HCC). METHODS: We performed 371 hepatic resections in HCC patients whom we categorized into two groups based on BMI: BMI ≥ 25 (n = 77) and BMI <25 (n = 294). We compared surgical outcomes between groups. RESULTS: The incidence of postoperative complications in the BMI ≥ 25 group was comparable to those in the BMI <25 group. However, patients in the BMI <25 group showed a significantly worse long-term prognosis than those in the BMI ≥ 25 group (P < 0.01). The results of multivariate analyses showed that BMI <25 was an independent and prognostic indicator of long-term outcome after hepatic resection in HCC patients. CONCLUSIONS: A BMI ≥ 25 is not a risk factor for mortality or postoperative complications, and is considered to provide a better long-term prognosis (>20 y) than a BMI <25 in patients with HCC after hepatic resection. Further studies are needed to determine whether these results apply to other patient populations outside Japan where BMI ≥ 30 is more prevalent.

A two-step hanging maneuver for a complete resection of Couinaud's segment I.

BACKGROUND: A hepatic resection of Couinaud's segment I is a challenging procedure because it is located deep in the abdominal cavity and surrounded by large blood vessels. A new technique, called the 'two-step hanging maneuver,' was applied to completely resect Couinaud's segment I. METHODS: A 59-year-old male was diagnosed with hepatocellular carcinoma in Couinaud's segment I. A hanging tape was positioned from the groove between the middle and left hepatic veins to the groove between the right and left Glisson sheaths via the posterior hepatic surface after all short hepatic veins were divided. The liver was split into the left and right hemilivers (step 1). The hanging tape was positioned into the fissure of the ligamentum venosus, then Couinaud's segment I was completely resected after dividing the liver parenchyma between segments I and IV by hanging the tape medially (step 2). RESULTS: The operation time was 435 min. No blood transfusions were necessary and there were no complications. CONCLUSION: This technique allowed resection of a tumor located in Couinaud's segment I without mobilization of the tumor and safely divided the liver parenchyma via only an anterior approach.

Quality of life after laparoscopy-assisted pylorus-preserving gastrectomy: an evaluation using a questionnaire mailed to the patients.

PURPOSE: This study investigated the postoperative quality of life (QOL) after laparoscopy-assisted pylorus-preserving gastrectomy (LAPPG) in comparison to laparoscopy-assisted distal gastrectomy (LADG). METHODS: Twenty-one patients with early-stage gastric cancer underwent minimally invasive LADG (n = 12) or LAPPG (n = 9). Demographic and cancer-related data were obtained retrospectively from medical records. QOL was assessed using a 13-item questionnaire and the Japanese edition of the Gastrointestinal Symptom Rating Scale, which were mailed to patients twice postoperatively. Body weight and hemoglobin levels were measured at the same time. RESULTS: Early upper abdominal pain was rated as significantly worse with LAPPG than with LADG at the first checkup (1.4 vs. 1.0, P = 0.02) but not at the second checkup (1.3 vs. 1.0, P = 0.07). There was a trend toward less body weight loss in the LAPPG patients in comparison to the LADG patients. The serum hemoglobin levels of LAPPG patients at the second checkup showed significantly higher than LADG patients (13.3 vs. 11.6 g/dL, P < 0.05). CONCLUSIONS: LAPPG and LADG produce similar QOL in patients. Trends toward less body weight loss and improved anemia in LAPPG patients may therefore become more pronounced in future studies that have adequate number of the patients and longer follow-up periods.

Prognostic effects of oral anti-cancer drugs as adjuvant chemotherapy for 2 years after gastric cancer surgery.

PURPOSE: We conducted this retrospective study to evaluate the effectiveness of giving oral anti-cancer drugs for 2 years as postoperative adjuvant chemotherapy to gastric cancer patients. METHODS: The subjects were 76 patients with stage II and III gastric cancer, who underwent curative surgery between 1989 and 2008. We divided the 20 years chronologically into the UFT term (1989-2003) and the S-1 term (2004-2008). The patients from each term were then divided into three groups according to the length of drug administration; namely, the surgery alone group, the 1-year group, and the 2-year group. RESULTS: The survival time of the 2-year group was better than that of the surgery alone group, not only in the UFT term, but also in the S-1 term (P = 0.0224). Longer relapse-free survival was evident in the S-1 term, especially for the 2-year group (P = 0.0110). A multivariate analysis showed both the stage of the cancer and 2 years of postoperative adjuvant chemotherapy to be independent factors predictive of prolonged survival (P = 0.0040 and P = 0.0022, respectively). CONCLUSIONS: The 2-year administration of oral anti-cancer drugs as postoperative adjuvant chemotherapy might improve the outcome of stage II, III gastric cancer patients. Randomized control trials are warranted to prove the effectiveness of this 2-year regimen.

[The operated case of 89 year-old patient with pleomorphic carcinoma of the lung].

A-89-year-old male patient who complained dry cough was detected lung mass of 3 cm size in diameter at the right upper lobe by CT. FDG-PET seemed to show hilar and mediastinum lymph nodes metastasis. After three weeks, the mass showed rapid growth with 5 cm diameter in size at CT. Therefore the original tumor was supposed to be undifferentiated carcinoma, above all, pleomorphic carcinoma. He had been done pulmonary resection after short period. The right upper lobectomy with combined resection of the partial middle lobe was performed. Hilar and mediastinum lymph nodes dissection was added. In pathological examination, the tumor was proved pleomorphic carcinoma, however, no lymph node metastasis was recognized. He did not refer any complications and discharged back home at the post-operative 11th day. Pleomorphic carcinoma of the lung is known to be difficult to obtain definite diagnosis in early stage because of rapid growth. Therefore many cases are detected in advanced stage. In addition, chemotherapy is generally not effective, so only operative resection seems to be useful. Our patient was 89-year-old, he tolerated the operation and was alive with no trouble during 6 months after resection. When complete resection seems to be possible, operation should be regarded as an initial treatment.
