Long-term survival after extended surgical resection of intrahepatic cholangiocarcinoma with extensive lymph node metastasis

We present a case of long-term survival in a patient that involved intrahepatic cholangiocarcinoma that metastasized to the paraaortic lymph nodes. A 62-year-old man underwent extended left hepatic lobectomy with caudate lobe resection, extrahepatic bile duct resection, portal vein resection and reconstruction, and middle hepatic vein resection and reconstruction with lymph node dissection for a liver tumor that was located in the caudate lobe. Histological examination of the resected specimen revealed moderately differentiated adenocarcinoma compatible with cholangiocarcinoma, and lymph node metastases were found in the area of the hepatoduodenal ligament and the paraaortic region. After surgical resection, recurrence was detected twice in the lymph nodes at the site of the left supraclavicular region. These recurrent tumors were completely eliminated by systemic chemotherapy with cisplatin or mitomycin C. The patient is now doing well 6 years and 5 months after surgical treatment. In this case, there was only one tumor, and the preoperative serum carbohydrate antigen 19-9 level was normal. In addition, heterozygosity was retained at the loci on chromosome 8p. These findings suggested that tumor in the present case was less aggressive, despite the nodal spread. The extensive surgical approach may have contributed to the long-term survival of this patient, while the recurrent tumor was sensitive to antitumoral agents.     

Six-year survival following left hepatic trisectionectomy with simultaneous resection of the portal vein and right hepatic artery for advanced perihilar cholangiocarcinoma without lymph node metastases: report of a case

We report a case of survival for more than 6?years following left hepatic trisectionectomy and caudate lobectomy with simultaneous resection of the portal vein and right hepatic artery. The patient was a 65-year-old woman admitted to a local hospital with obstructive jaundice. The patient was diagnosed with perihilar cholangiocarcinoma and referred to our hospital. The tumor was located mainly in the left hilar region and occluded the left portal vein; furthermore, it involved the right portal vein and the right hepatic artery. The patient underwent left hepatic trisectionectomy and caudate lobectomy with simultaneous resection of the portal vein and right hepatic artery. The histological findings revealed that the tumor had invaded the portal vein and surrounded the right hepatic artery without any lymph node metastases. Microscopic curative (R0) resection was achieved. The patient is now healthy and still alive 6?years and 6?months after the surgery without any recurrence. Precise preoperative evaluation of the tumor and R0 resection by extended surgery contributed to a satisfactory outcome.     

Aggressive surgery for stage IV gallbladder carcinoma; what are the contraindications?

Background/Purpose

Advanced gallbladder carcinoma with paraaortic lymph node metastasis or distant metastasis is normally considered a contraindication for surgery. Our latest analyses suggest otherwise.

Methods

Records of 166 patients who underwent surgery for stage IV gallbladder carcinoma were reviewed retrospectively. Predictors of hospital mortality and long-term survival were analyzed. Long-term survival in patients with paraaortic lymph node metastasis and/or distant metastasis was also determined.

Results

Fifteen patients were 5-year survivors, with a 5-year survival rate of 12% among the 166 patients investigated. Overall hospital mortality was 14%. Male sex and portal vein resection were independent predictors of hospital mortality. Multivariate analysis of long-term survival failed to identify independent predictors. Patients with distant metastasis were divided into two groups based on whether or not the metastases were distant from the liver. Patients with paraaortic lymph node metastasis who underwent curative resection or who had isolated liver metastasis survived longer than those with other distant metastasis or those with unresectable advanced cancer.

Conclusions

Patients with advanced gallbladder carcinoma can benefit from surgical resection even when paraaortic lymph node metastasis and/or liver metastasis are present. However, surgical indications in advanced disease should be determined on an individual basis, based on clinical status.     

Eight-year survival after advanced gastric cancer treated with S-1 followed by surgery

We report a case of advanced gastric cancer, with cervical, axillary, and abdominal paraaortic lymph node metastases, that was successfully treated with chemotherapy and surgery. The disease was initially considered unresectable, and the patient was treated with orally administered S-1. Chemotherapy was effective, and all lymph node metastases disappeared after 6 courses. After 27 mo of chemotherapy, the patient underwent curative surgery, with subtotal gastrectomy and lymph node dissection. Histopathologic...     

A surgically treated case of hepatocellular carcinoma with extensive lymph node metastases

A 62-year-old man with chronic hepatitis C was found to have a hepatic tumor by ultrasonography. Computed tomography of the liver disclosed a tumor 4 cm in diameter occupying the posterior segment and associated with a portal tumor thrombus and enlargement of hilar and paraaortic lymph nodes. At laparotomy multiple nodal metastases were seen involving hilar, hepatoduodenal, common hepatic arterial, and paraaortic nodes. We performed right hepatic lobectomy and systematic lymph node dissection. Histologic examination of both the main tumor and nodal metastases showed poorly-differentiated hepatocellular carcinoma. Severe postoperative ascites persisted for 1 month. Fifteen months after surgery the patient died of multiple intrahepatic and systemic nodal recurrences. Our experience confirms that surgical treatment of hepatocellular carcinoma with nodal metastases is likely to benefit only a few carefully selected patients, since the prognosis is commonly poor and hepatectomy with lymph node dissection carries the risk of severe complications.     

The role of lymphatic drainage of the liver in gallbladder cancer: a case report.

We report a case of a patient with a unique lymph node relapse after right hepatectomy and aggressive lymph node dissection for gallbladder cancer. There was extensive involvement of the hepatic parenchyma from the primary tumor, but no extension to the lymph nodes or other adjacent organs. Seventeen months later, the patient underwent re-dissection of the retroperitoneal lymph nodes with right nephrectomy and partial resection of the vena cava because of lymph node recurrence at the hilum of the right kidney. This pattern of lymph node metastasis to the right side of the vena cava from gallbladder cancer invading the liver is probably due to the distinct lymphatic drainage of the liver.     

Metastasis of hepatocellular carcinoma to the supramaxillary gingiva and right ventricle

We describe a rare double metastasis of hepatocellular carcinoma to the supramaxillary gingiva and papillary muscle of the right ventricle. The patient was a 72-year-old woman who underwent three sessions of transcatheter arterial embolization for the primary lesions. Control of bleeding from the supramaxillary gingival metastasis was difficult by conservative treatment such as compression with gauze soaked in epinephrine. Therefore, radiotherapy was performed, but it failed to control the bleeding. The patient subsequently died due to hepatic failure. Autopsy revealed metastases of hepatocellular carcinoma to the papillary muscle of the right ventricle and paraaortic lymph node in the abdomen in addition to the supramaxillary gingival metastasis. Histopathological examination showed moderately differentiated hepatocellular carcinoma of both the primary site and metastatic sites to the gingiva and the heart and poorly differentiated in the paraaortic lymph node.     

The pattern of lymph node involvement in carcinoma of the head of the pancreas

Summary To clarify the pattern of lymph node metastasis in carcinoma of the pancreas, lymph node involvement was examined in forty-two patients who underwent extensive nodal dissections, including the paraaortic lymph nodes. The correlation between the spread of the tumor and lymph node involvement was evaluated: The most common site of involved lymph nodes was the retropancreatic region. The prevalence of nodal metastases was 78.6%. Metastases to the paraaortic region were present in seven patients, among whom metastases in the paraaortic region were most common in the median region from the celiac artery to the inferior mesenteric artery and in the space between the aorta and the vena cava. The risk of lymph node metastases tended to increase with tumor size, except in the paraaortic region, where the correlation between the frequency of metastasis and tumor size was poor. The probability of lymph node metastases increased with the degree of lymphatic invasion (ly) and the growth pattern of the tumor (INF) and was high in patients with invasion into the retropancreatic tissue and in tumors with scirrhous histology. These results indicate that even in small cancers, lymph nodes of the paraaortic region frequently harbor metastases and should be dissected en block during radical resections of pancreatic cancer.     

Cardiac metastasis from squamous cell carcinoma of gallbladder

A 65-year-old woman was admitted to our hospital with the diagnosis of gallbladder tumor. Right extended hepatic lobectomy plus lymph node dissection of the hepatoduodenal ligament and left hepaticojejunostomy with Roux-en-Y reconstruction was performed in July, 1993. The gallbladder tumor was histologically proven to be squamous cell carcinoma. Seventeen months later, the patient experienced dyspnea and pitting edema of the lower legs and was admitted, in December 1994, with a diagnosis of heart failure. Despite intensive cardiac support, she died 12 days after the second admission. Autopsy revealed multiple cardiac tumors in the left and right ventricles, left atrium, left coronary artery, and left diaphragm. Histologically, these tumors were shown to be squamous cell carcinoma, considered to have metastasized from the primary gallbladder carcinoma. As neither local recurrence of the gallbladder carcinoma. As neither local recurrence of the gallbladder carcinoma nor any lymph node metastasis was found, the cardiac metastasis of the gallbladder carcinoma may have occurred via the hematogenous route. Although rare, this route of cardiac metastasis of gallbladder carcinoma may be an important aspect of distant metastasis, which should be monitored for during follow-up after resection of the primary tumor.     

Studies on hepatobiliary lymph flow with radioactive colloid--for lymph node metastasis resection of carcinoma of the bifurcation of hepatic duct

Hepatobiliary lymphoscintigraphy by Technetium 99m-rhenium colloid (99mTc-Re colloid) using a fine needle guided by ultrasonography was performed on 12 patients who underwent resection of the hepatoduodenal ligament lymph nodes. Histological examination revealed no lymph node metastasis in 8 patients. In 4 patients in whom 99mTc-Re colloid was injected into the left medial inferior hepatic segment, periarterial lymph nodes showed higher isotope uptake count than periductal nodes, and lymph nodes around the common hepatic artery revealed higher values than superior posterior pancreatoduodenal nodes. On the contrary, in 3 patients in whom the isotope was injected into the right anterior inferior segment, periductal lymph nodes had higher values than periarterial nodes, and superior posterior pancreatoduodenal lymph nodes showed higher values than those around the common hepatic artery. In one patient in whom the isotope was injected into both right and left segments, superior posterior pancreatoduodenal lymph nodes showed similar values to those around the common hepatic artery. Periportal lymph nodes tended to have values between those of periarterial and periductal ones. Lymph node metastases were confirmed in 4 patients in whom the relationships mentioned above was not always observed, and periportal lymph nodes showed the highest values among the three.     

A case of recurred small hepatocellular carcinoma as a solitary lymph node metastasis after hepatic resection]

Extrahepatic recurrence of hepatocellular carcinoma (HCC) has been considered unsuitable for surgical resection since the disease is considered to be extensive. However, solitary local lymph node recurrence in small HCC is rarely reported with suitable treatment modality being uncertain. We herein, present a case of 60-year-old female patient with small HCC showing late lymph node metastasis after complete resection of primary HCC. A 2 cm-sized hepatic mass was completely resected by segmentectomy (VIII). Eight months later, CT and PET scan revealed a 4.5 cm-sized portocaval lymph node (LN). In addition, whole body PET/CT scan strongly suggested a solitary tumor recurrence. Radical lymphadenectomy was performed. Tumor was confirmed as LN metastasis from HCC by excisional histopathological examination. Adjuvant chemotherapy and radiotherapy were followed.     

The successfully curative treatment of advanced gastric adenocarcinoma with multiple liver metastases and paraaortic lymph node metastases by salvage operation following the biweekly paclitaxel and S-1 combination chemotherapy: a case report

We report the case of 67-year-old man who was given a diagnosis of advanced gastric adenocarcinoma. Complete response of multiple liver and paraaortic lymph node metastases occurred in this patient after combination chemotherapy with systemic injection of paclitaxel and oral administration of novel dihydropyrimidine- dehydrogenase- inhibitory fluoropyrimidine (S-1). Following 7 courses of the biweekly paclitaxel and S-1 combination chemotherapy, the patient underwent total gastrectomy with D3 extended lymph node dissection. According to the operative findings, the tumor was curatively removed along with the liver metastases and paraaortic lymph node metastases. Biopsy of the liver was performed and the pathological diagnosis indicated no gastric adenocarcinoma cells. The pathological report showed that the lymph node metastases had completely disappeared with single exception and minute cancerous lesions were identified in the gastric mucosa and submucosa. Therefore, the histological efficacy was evaluated as Grade 2. For postoperative chemotherapy, oral S-1 administration only was chosen. However, 6 months later, biweekly paclitaxel and S-1 combination chemotherapy was administered in sequence as a second adjuvant chemotherapy because the serum level of the tumor marker was elevated. The patient is fine and has not shown any recurrence at other sites 37 months after surgery. Salvage surgery following paclitaxel and S-1 chemotherapy may be feasible for patients with advanced gastric cancer and complete regression of distant metastases. Biweekly paclitaxel and S-1 combination chemotherapy has been used safely and its administration may be continued for a long time in an outpatient clinic setting for the treatment of advanced gastric cancer.     

Abnormal arrangement of the pancreato-biliary ductal system associated with advanced gallbladder cancer diagnosed 3 years after follow-up ultrasonography

We herein report a case of abnormal arrangement of the pancreato-biliary ductal system (AAPB) followed by advanced gallbladder cancer 9 years after the initial endoscopic retrograde cholangiopancreatography (ERCP) diagnosis and almost 3 years after follow-up ultrasonography (US). A 65-year-old woman was referred to our department from a private clinic because of difficulty in controlling her diabetes mellitus. The patient had no complaints, and physical examination revealed no jaundice in her skin or conjunctiva. ERCP demonstrated the presence of AAPB (bile duct-main type) without congenital dilatation of the bile duct or irregularity in the gallbladder wall. She did not wish to undergo cholecystectomy. Follow-up transabdominal US revealed no change in the gallbladder. Two years and 9 months after this US examination, she developed advanced gallbladder cancer involving the liver and bile duct, with paraaortic lymph node metastases confirmed by US, computed tomography, and ERCP. This case re-emphasizes the necessity for patients with AAPB to undergo intensive follow-up examinations or cholecystectomy when the diagnosis of AAPB has been established.     

Deep vein thrombosis caused by pelvic lymphocyst following radical prostatectomy: a case report

A 66-year-old man was admitted with distal edema of his right leg. He had undergone radical prostatectomy and pelvic lymphadenectomy for prostatic cancer 23 days previously. Abdominal computed tomography (CT) showed a lymphocyst (4.5 x 3.0 cm) along the right pelvic wall compressing the right external iliac vein. CT with contrast medium showed thrombus formation (about 9 cm) in the distal portion of the right external iliac vein and femoral vein. An inferior vena cava filter was placed to prevent pulmonary embolism, and anticoagulation with warfarin was started. One week later, CT showed shrinkage of the lymphocyst and thrombus in the vein, as well as a large thrombus trapped in the filter. Follow-up CT taken 2 months later revealed marked reduction of the lymphocyst and absence of thrombus in both the vein and filter. A lymphocyst, also known as a lymphocele, is a complication of radical pelvic surgery. Most lymphocysts are asymptomatic and regress spontaneously, but may lead to deep vein thrombosis and pulmonary embolism, usually a few weeks after surgery. Careful observation is needed even after discharge from hospital.     

Small-cell carcinoma manifesting systemic lymphadenopathy combined with adenocarcinoma in the gallbladder: aggressiveness and sensitivity to chemotherapy

Small-cell carcinoma of the gallbladder is a very rare tumor. In this report, we describe a patient with small-cell carcinoma combined with adenocarcinoma in the gallbladder. The patient was a 70-year-old man, who clinically manifested systemic lymphadenopathy. An incisional biopsy of Virchow's lymph node revealed small-cell carcinoma. Abdominal computed tomography (CT) showed massive multiple paraaortic lymph node swelling and a round mass in the gallbladder, although chest CT did not show any abnormal masses in the lung. After two courses of chemotherapy (PVP therapy; cisplatin [CDDP], 80mg/m², day 1, intravenous injection; and etoposide [VP-16], 50mg/m², every day, per oral intake; given every 3 weeks) were performed, the systemic lymphadenopathy had completely diminished and only the gallbladder tumor remained on clinical examinations. Endoscopic retrograde cholangiopancreatography (ERCP) revealed nodular tumors in the gallbladder fundus. Cholecystectomy with partial resection of the liver was performed. Pathological examination revealed small-cell carcinoma combined with adenocarcinoma of the gallbladder. We discuss the characteristics and the treatment of this rare tumor.     

Signet ring cell carcinoma of the stomach--a case of diagnostic dilemma

Inguinal lymphonodal metastases of an adenocarcinoma were diagnosed in a 40-year-old patient by ultrasound guided puncture. The leading symptom was elephantiasis preferentially of the right lower extremity. In addition, atypical mycobacteriosis was detected later on. The causal gastric cancer had not been identified during two years until the fourth gastroscopy assisted by endoscopic ultrasonography revealed the lesion. No regional lymph node metastases were found while distant metastases in terms of inguinal lymph nodes were already present.     

Axillary lymph node metastasis following resection of abdominal wall laparoscopic port site recurrence of gallbladder cancer

Abdominal wall port site recurrence of gallbladder cancer is well described in the literature in patients that have undergone laparoscopic cholecystectomy with the incidental finding of a gallbladder cancer. The etiology and consequences of this type of metastatic recurrence are unclear. This report describes two cases with the unique sequelae of the interval development of nodal metastases to the axillary lymph nodes following resection of an abdominal wall laparoscopic port site recurrence of gallbladder cancer. The first case involves a patient who developed an isolated left axillary lymph node metastasis approximately 10 months after undergoing resection of a left-sided abdominal wall port site recurrence for a T2 gallbladder cancer. The original tumor had been found at laparoscopic cholecystectomy and definitively treated surgically approximately 3 years earlier. The second case involves a patient who developed isolated nodal metastases to the right axillary lymph nodes approximately 4 months after undergoing resection of right-sided abdominal wall port site recurrence, segment 4/5 hepatic resection, and portal lymphadenectomy for a T2 gallbladder cancer. This tumor had originally been found at laparoscopic cholecystectomy approximately 1 year earlier. These unique sequelae of the interval development of nodal metastases to the axillary lymph nodes demonstrated in both cases has not been previously reported.     

An elderly case of advanced gastric cancer with gynecomastia and high serum levels of hCG

A 74-year-old man was admitted because of appetite loss in November 1999. A gastric ulcer was diagnosed, and a H2 blocker was given. He had had appetite loss since July 1997 and had experienced epigastric discomfort since October of 1997. On admission, hepatic and pancreatic lymph node swelling was detected by ultrasonography of the abdomen. Physical examination revealed a palpable mass in the middle region of the upper abdomen as well as gynecomastia. Laboratory findings showed high serum levels of hCG (11,700 mIU/ml) and high urinary levels of hCG (1,600 mIU/ml). Upper gastrointestinal endoscopy showed a gastric cancer of Borrmann type 3 in the posterior wall of the middle body. A biopsy revealed a moderately differentiated adenocarcinoma. hCG immunoreactivity was not seen in the cancer tissue. A contrast-enhanced CT scan of the abdomen revealed multiple lymph node swelling in the hepatic and pancreatic lymph nodes. There was a low-density area suggesting liver metastases. No other primary carcinomas were not detected. We believe that the gynecomastia was due to the hCG-producing tumor. The patient died 2 months after diagnosis.     

A case of antiphospholipid syndrome associated with left subclavian artery thrombosis and left external iliac vein thrombosis]

Arterial thrombosis is one of the major symptoms of antiphospholipid syndrome (APS). However, thrombosis in a primary branch of the aorta has rarely been reported in APS. We report here a case of APS complicated by thromboses in both the left subclavian artery and the left external iliac vein. A 32-year-old woman was admitted in May, 1990 complaining of no pulse in the left superficial arteries (e.g., left radial artery) for the past 5 years and acute swelling of the left lower extremity. A left ascending phlebography showed an occlusion of the external iliac vein and arteriography revealed obstruction in the left subclavian artery. Collateral circulations were developed at the site of each thrombus. Clotting and immunological studies revealed a prolonged APTT, a high titer of anticardiolipin antibody and lupus anticoagulant positive. We ruled out various diseases and clinical risk factors predisposing to both arterial and venous thromboses. Accordingly, we concluded that both thromboses were based on APS. Following treatment with anticoagulants, aspirin and corticosteroid, the swelling of her left thigh was diminished and the antibody titer was decreased within 3 months.     

Intrahepatic Lymphatics Opacified during Hepatic Arteriography in a Patient with Hepatocellular Carcinoma

Extrahepatic lymph node metastases are not uncommon in advanced cases of hepatocellular carcinoma (HCC). This is the account of a HCC case in which intrahepatic lymphatics running toward the hepatic hilus were clearly opacified during hepatic arteriography. The patient was treated by hepatic artery embolization followed by selective embolization of the portal branches, but lymph node metastases at the hepatic hilus were later found during follow-up. The clinical course of this case suggests that the communication between the tumor and the lymphatics was responsible for the lymph node metastasis.
