RESUMO
BACKGROUND: Venous thromboembolism (VTE) is highly associated with advanced gastric cancer (AGC) and is sometimes lethal. Predictors of VTE have not been identified, and the efficacy and safety of direct oral anticoagulants (DOACs) for AGC-associated VTE remain to be clarified. METHODS: A total of 188 AGC patients who started chemotherapy during the period from January 2014 to December 2017 in our institutions were retrospectively examined for the incidence of VTE, risk factors for VTE, and the efficacy and safety of DOAC-based anticoagulant therapy for VTE. RESULTS: Thirty-four patients (18%) were diagnosed with VTE at the start or during the course of chemotherapy (VTE group). More VTE group patients had a history of abdominal surgery and had moderate-severe ascites (32% versus 17%, 32% versus 14%, respectively) than non-VTE group patients (NVTE group). The mean serum albumin concentrations in the VTE group were significantly lower than NVTE group (3.38 mg/dL vs 3.65 mg/dL, respectively). Multivariate analysis showed that hypoalbuminemia was significantly correlated with VTE (P = 0.012). In the VTE group, 29 patients (85%) received anticoagulant therapy, including 24 patients treated with DOACs. No lethal VTE was observed in any patients. Thirteen patients (45%) terminated DOACs because of anemia or bleeding events, of whom eleven developed major bleeding. Median overall survivals of the VTE and NVTE groups were 9.63 months and 11.5 months, respectively (P = 0.262). CONCLUSION: Hypoalbuminemia appears to be a risk factor for AGC-associated VTE. DOACs are effective to AGC-associated VTE, but careful observation of bleeding events is required.

BACKGROUND: Dose modification of chemotherapy for metastatic colorectal cancer (MCRC) is often needed, especially in second-line and later-line treatments due to adverse events of previous treatment and poor patient condition. No study has focused on ramucirumab plus modified dose of FOLFIRI for MCRC, and whether low relative dose intensity (RDI) affects treatment efficacy has not been clarified. METHODS: MCRC patients who received ramucirumab plus FOLFIRI, which consisted of 150 mg/m2 of irinotecan, at six institutions were retrospectively analyzed. RESULTS: A total of 43 patients were assessed. Median age was 63 years, and 22 patients (51%) were women. Twenty-six patients (60%) were given ramucirumab plus FOLFIRI as second-line therapy, and 17 (40%) as third or later-line. The median relative dose intensity (RDI) of irinotecan was 60.6%, which is lower than that in the pivotal phase 3 study (RAISE), and other agents showed the same trend. Median progression-free survival was 4.8 [95% confidence interval (CI) 3.2-5.7] months for all patients, 5.4 (95% CI 3.5-7.2) months for second-line patients, and 2.8 (95% CI 1.6-5.8) months for third or later-line patients. Median overall survival was 17.3 (95% CI 11.5-22.4) months for all patients. Patients with irinotecan RDI less than 60% showed similar treatment efficacy. Hematological toxicities of grade 3 or worse were observed in 21 patients, but all were manageable. CONCLUSION: Low RDI did not compromise the treatment efficacy of ramucirumab plus modified FOLFIRI for MCRC patients.

Disseminated cancer cells in malignant ascites possess unique properties that differ from primary tumors. However, the biological features of ascites tumor cells (ATC) have not been fully investigated. By analyzing ascites fluid from 65 gastrointestinal cancer patients, the distinguishing characteristics of ATC were identified. High frequency of CD44+ cells was observed in ATC using flow cytometry (n = 48). Multiplex quantitative PCR (n = 15) showed higher gene expression of epithelial-mesenchymal transition (EMT)-related genes and transforming growth factor beta (TGF-beta)-related genes in ATC than in the primary tissues. Immunohistochemistry (n = 10) showed that ATC also had much higher expression of phosphorylated SMAD2 than that in the corresponding primary tissues. TGF-beta 1 was detected in all cases of malignant ascites by enzyme-linked immunoassay (n = 38), suggesting the possible interaction of ATC and the ascites microenvironment. In vitro experiments revealed that these ATC properties were maintained by TGF-beta 1 in cultured ATC(n = 3). Here, we showed that ATCrevealed high frequencies of CD44 and possessed distinct EMT features from primary tissues that were mainly maintained by TGF-beta 1 in the ascites.

PURPOSE: Peripheral sensory neuropathy (PSN) and thrombocytopenia are the main dose-limiting toxicities of oxaliplatin for the treatment of advanced gastric cancer (AGC). Because the risk factors for those toxicities in practice have not been clarified, we conducted this prospective study. METHODS: AGC patients who received oxaliplatin-based therapy at any of seven institutions participating in the Kyushu Medical Oncology Group were assessed after we obtained written informed consent. RESULTS: A total of 60 patients including 39 males and 21 females were examined. The median age was 66 years. The numbers of patients receiving oxaliplatin as the first, second, or third and later lines of therapy were 39, 16, and 5, respectively. An initial dose of 130, 100, or < 100 mg/m2 oxaliplatin was administered to 12, 39, and 9 patients, respectively. S-1 or capecitabine as a concomitant drug was administered in 54 and 6 patients, respectively. In multivariate analysis, the comorbidity of diabetes mellitus was associated with ≥ grade 2 thrombocytopenia (p = 0.035). No significant risk factor was associated with ≥ grade 2 PSN. However, the accumulated dose of oxaliplatin exhibited a strong correlation with ≥ grade 2 PSN (p = 0.0043), and the predicted accumulated dose of oxaliplatin in which 10% of patients developed ≥ grade 2 PSN was 800 mg/m2. The frequency of PSN in subsequent paclitaxel therapy in patients with ≥ grade 2 or worse PSN in oxaliplatin-based chemotherapy did not increase compared to those with none or grade 1 PSN in oxaliplatin. CONCLUSION: Thrombocytopenia in AGC patients with diabetes mellitus should be carefully monitored during oxaliplatin-based therapy.

PURPOSE: Combination therapy of fosaprepitant, dexamethasone (DEX) and a serotonin (5-HT3) receptor antagonist is a standard antiemetic prophylaxis for patients receiving highly emetogenic chemotherapy (HEC). However, the appropriate dose of DEX has not been established in Japan. This study determined the efficacy and safety of triplet antiemetic prophylaxis in Japanese patients receiving HEC when administered the same doses of DEX as those given in a previous international phase 3 study on this drug. METHODS: To assess the efficacy and safety of a sufficient dose of DEX (12âmg on day 1, 8âmg on day 2, 16âmg on days 3 and 4) in combination with intravenous fosaprepitant and granisetron, we prospectively examined patients receiving HEC including cisplatin (≥50âmg/m). The primary endpoint was to determine the percentage of patients who had achieved a complete response (CR), which was defined as no vomiting and no rescue therapy during the entire treatment course. RESULTS: Between February 2013 and January 2015, 44 patients were enrolled with a median age of 65 years (range, 30-75). There were 34 males (77.3%) in the study. Most of the patients had upper gastrointestinal cancers. The CR rate during the treatment course was 70% (95% confidence interval [CI]: 55%-83%) in the overall phase and 91% (95% CI: 78%-97%) in the acute phase and 70% (95% CI: 55%-83%) in the delayed phase. Appreciable severe toxicities related to the antiemetic therapy were not observed. CONCLUSIONS: These results suggest that a sufficient dose of DEX in combination with fosaprepitant and granisetron is optimal as an antiemetic prophylaxis for Japanese patients receiving HEC.

RATIONALE: Metastatic littoral cell angioma (LCA) is extremely rare. No standard therapeutic strategy has been established, and the impact of chemotherapy has not yet been evaluated. PATIENT CONCERNS: A 61-year-old woman was admitted because of bicytopenia. She had a splenectomy for LCA of the spleen 10 years earlier. Bone marrow aspiration was normal, and a computed tomography (CT) scan showed hepatomegaly with multiple liver tumors. DIAGNOSES: Liver biopsy samples showed macrophage-like cell infiltration in the hepatic sinusoids. Metastatic LCA was diagnosed based on immunohistochemistry, imaging tests, and the clinical course. INTERVENTIONS: Immunosuppressive agents, such as prednisolone and cyclosporine, were ineffective. Next, cytotoxic agents, such as etoposide, paclitaxel, and vincristine, were administered. OUTCOMES: Cytotoxic agents showed a prominent effect against LCA. CT showed improvement of the hepatomegaly, and fluoro-deoxyglucose (FDG) uptake decreased markedly at a follow-up FDG- positron emission tomography (PET) scan. LESSONS: Chemotherapeutic treatment based on hemophagocytic syndrome or angiosarcoma might have anti-tumor activity against metastatic LCA. Analysis of the molecular characteristics of this tumor is needed to develop better treatment options.

RATIONALE: Neurogenic shock is generally typified by spinal injury due to bone metastases in cancer patients, but continuous disturbance of the vagus nerve controlling the aortic arch baroreceptor can cause shock by a reflex response through the medulla oblongata. PATIENT CONCERNS: A 43-year-old woman with dysphagia presented to our hospital. Computed tomography showed a primary tumor adjacent to and surrounding half the circumference of the descending aorta, and multiple cervical lymph node metastases, including a 55â×â35-mm lymph node overlapping the root of the left vagus nerve. Squamous esophageal cancer (T4bN3M1, stage IV) was diagnosed. Whereas shock status initially appeared soon after left cervical pain, suggesting pain-induced neutrally-mediated syncope, sustained bradycardia and hypotension occurred even after alleviation of pain by opioids. DIAGNOSIS: Disturbance of the left vagus nerve associated with the aortic arch baroreceptor by a large left cervical lymph node metastasis was considered as the cause of shock, pathologically mimicking the baroreceptor reflex. INTERVENTIONS: Systemic steroid administration was performed, and radiotherapy for both the primary site and lymph node metastasis was started 2 days after initiating steroid treatment. OUTCOMES: Four days after initiating steroid administration, hypotension and bradycardia were improved and stable. LESSONS: Disturbance of the vagus nerve controlling the aortic arch baroreceptor should be kept in mind as a potential cause of neurogenic shock in cancer patients, through a pathological reflex mimicking the baroreceptor reflex.

RATIONALE: Regorafenib is effective for metastatic colorectal cancer but its toxicity such as hemorrhage should be considered. The safety of regorafenib for the patient with the liver disease is not known. PATIENT CONCERNS: Seventy-one-year old man of colon cancer had myodesopsia and blood stool after 14 days from the initiation of regorafenib administration with 50% dose reduction due to liver dysfunction. DIAGNOSES: Fundus examination revealed hemorrhage of the retinal vein. INTERVENTIONS: Regorafenib treatment was discontinued and observational therapy was pursued. OUTCOMES: Retinal and gastrointestinal hemorrhage resolved in 1 week. LESSONS: Retinal hemorrhage should be considered as the differential diagnosis of myodesopsia in the patient treated by regorafenib. Safety and pharmacokinetic of continuous regorafenib administration for patients with liver dysfunction remains to be clarified.

An advanced granulocyte-colony stimulating factor (G-CSF)-producing tumor is rare, and it exhibits leukocytosis in association with high serum G-CSF levels. A 67-year-old male with a 1-month history of bloody emesis and black stools was revealed to exhibit leukocytosis, anemia and a high serum concentration of G-CSF. During a gastrointestinal endoscopy, an ulcerating tumor was identified in the stomach. Computed tomography and a fluorodeoxyglucose-positron emission tomography scan demonstrated direct invasion of the gastric tumor into the transverse colon, regional lymphadenopathy, lung nodules and diffuse high uptake of FDG in bone marrow. The histological diagnosis was a G-CSF-producing neuroendocrine carcinoma (NEC) (tumor 4b, node 2, metastasis 1, pulmonary, clinical stage IV). Systemic chemotherapy consisting of cisplatin and irinotecan was started. Common terminology criteria of adverse events grade 3 tumor lysis syndrome and gastric penetration appeared. Grade 4 neutropenia lasted for 10 days despite intensive G-CSF administration. Prominent shrinkage of the primary and the metastatic tumors was observed subsequent to 3 cycles of chemotherapy. Total gastrectomy and resection of the transverse colon were subsequently performed. Systemic chemotherapy was effective for a G-CSF-producing advanced gastric NEC with careful monitoring and appropriate supportive care for severe adverse events.
RESUMO
PURPOSE: Standard therapy for advanced small bowel adenocarcinoma (SBA) has not yet been established. The present study assessed the efficacy and safety of chemotherapy (CT) in association with molecular targeting approaches for SBA. METHODS: The histories of 33 advanced SBA patients from six different institutions in Japan, who received CT from 2008 to 2016, were retrospectively examined for background, clinical course and outcome. RESULTS: Median patient age was 65 years (range 39-83). Primary tumor was located in the duodenum in 21 patients (67%), the ampulla of Vater in three patients (9%), the jejunum in seven patients (21%) and the ileum in one patient (3%). Histologically, well-to-moderately and poorly differentiated adenocarcinoma were identified in 20 (61%) and nine (27%) patients, respectively. Thirteen patients received a single CT regimen, seven patients received two types of CT regimen, and 13 patients received three or more CT regimens. As first-line CT, modified FOLFOX6, capecitabine plus oxaliplatin, and S-1 plus cisplatin were employed in 13, 1, and 4 patients, respectively. The response rate (RR) and median progression-free survival (PFS) were 25% and 6.0 months, respectively. Median overall survival (OS) was 13.0 months. Nine out of the 33 patients received bevacizumab-containing CT and three received cetuximab-containing CT. Median OS of bevacizumab-containing CT patients was 21.9 months. No unexpected serious adverse events were observed. CONCLUSIONS: The analysis indicates that combination CT for advanced SBA is associated with modest efficacy and safety, and bevacizumab-containing CT may contribute to favorable outcome in these patients.

BACKGROUND: Significant efficacy of oxaliplatin-based chemotherapy has been demonstrated for advanced gastric cancer (AGC). However, the appropriate dose of oxaliplatin, and the efficacy and toxicity of administration of oxaliplatin subsequent to cisplatin therapy still remain unclear. PATIENTS AND METHODS: In total, 55 patients with AGC that were scheduled to receive oxaliplatin-based chemotherapy were prospectively examined. RESULTS: The median age was 67 years and oxaliplatin was administered to 39 (71%) patients as first-line and in 16 (29%) patients as second-line therapy. An initial dose of 130 or 100 mg/m2 of oxaliplatin was administered to 11 and 36 patients, respectively. The overall response rates (ORR) and median progression free survival (mPFS) were 86 and 33%, and 7.2 and 7.8 months, respectively. Compared to 100 mg/m2, the relative dose intensity was significantly lower and severe toxicity tended to increase with oxaliplatin at 130 mg/m2 A total of 10 patients (18%) had a prior cisplatin-based therapy. The ORR of the patients pretreated with cisplatin was 14% and the mPFS was 6.1 months. CONCLUSION: An initial oxaliplatin dose of 130 mg/m2 resulted in a good response, but tended to increase the risk of toxicity. Subsequent oxaliplatin-based therapy after cisplatin exhibited modest efficacy, especially in cases with cisplatin intolerance.

Distant metastasis of primary squamous cell carcinoma (SCC) of the thyroid gland is rare and, to the best of our knowledge, cardiac metastasis has not been reported to date. A 57-year-old man underwent surgery and adjuvant chemoradiotherapy for stage IVA SCC of the thyroid gland. After 3 months, the patient was admitted to the Kyushu University Hospital (Fukuoka, Japan) with subcutaneous hematomas of the left thigh and lower leg, and he was diagnosed with cardiac and mediastinal lymph node metastases of SCC of the thyroid gland with severe disseminated intravascular coagulation (DIC). Echocardiography revealed a mass, 52 mm in greatest diameter, protruding from the interventricular septum towards the right ventricle. Weekly administration of paclitaxel and concurrent irradiation of the cardiac and lymph node metastases were performed. Eighteen days after the initiation of chemoradiotherapy, the DIC and hematomas had significantly improved, and the cardiac metastasis was stable. However, 2 months after admission, the patient developed dyspnea and multiple nodular shadows appeared to be spreading in the subpleura of the lungs bilaterally, which were initially suspected to be pulmonary tumor embolisms. Prednisolone and subsequent administration of lenvatinib were not effective and the patient succumbed to respiratory failure. Severe DIC caused by extremely rare cardiac metastasis of SCC of the thyroid gland was effectively controlled by chemoradiotherapy. However, intensive local control appears to be required for this condition.
RESUMO
BACKGROUND: Patients with advanced gastric cancer (AGC) often suffer weight loss, which can be used to predict prognosis. Few reports have assessed the correlation between weight loss during chemotherapy and survival in patients with AGC. METHODS: Fifty-three patients with histologically proven AGC, who started systemic chemotherapy from September 2010 to March 2014, were retrospectively examined for body weight, inflammatory status, and survival. Correlation analyses were performed between weight change and survival. Correlations between weight loss and the patient characteristics were analyzed by stepwise multiple regression analyses. RESULTS: The mean age of the patients was 64.4 years; 64% of the patients were males. Initial chemotherapy included fluoropyrimidine plus cisplatin (62%), fluoropyrimidine alone (26%), and other medications (12%); 72% of the patients exhibited weight loss during the initial therapy. Poorer mean overall survival and mean progression-free survival were observed in patients with weight loss of higher-than-average values than in those with weight loss of lower-than-average values. Serum C-reactive protein levels were significantly correlated with weight loss. CONCLUSIONS: Weight loss during initial chemotherapy for AGC may predict survival. Systemic inflammation is suggested to be associated with weight loss.

Appropriate antiemetic prophylaxis for moderately emetogenic chemotherapy in patients with non-round cell soft-tissue sarcomas (NRC-STS) remains unclear. We retrospectively investigated efficacy and safety of aprepitant-combined antiemetic prophylaxis in patients with NRC-STS receiving adriamycin plus ifosfamide (AI) therapy. Forty NRC-STS patients were enrolled, their median age was 50 years (range 18-74), and 13 (32.5%) were female. Median cycle number of AI therapy was 4. Twenty patients received the doublet antiemetic prophylaxis (5-hydroxytryptamine-3 receptor antagonist and dexamethasone), and 20 received triplet (5-hydroxytryptamine-3 receptor antagonist, dexamethasone, and aprepitant). In the overall period, complete response rate for nausea and emesis in the triplet group was significantly higher than that in the doublet group (70% vs 35%; P = 0.027). Patients with no-emesis in the overall period were more frequently observed in the triplet group than in the doublet group (90% vs 65%; P = 0.058). All toxicities other than emesis were almost equivalent in both the groups. These results suggest that a triplet antiemetic prophylaxis may be optimal in the treatment with AI therapy for NRC-STS.

BACKGROUND: Anti-programmed cell death 1 antibody nivolumab is a promising agent for various cancers. Immune-related adverse events are recognized; however, bi-cytopenia with nivolumab has not been reported. CASE PRESENTATION: A 73-year-old man was diagnosed with advanced primary malignant melanoma of the esophagus with liver, lung, and lymph node metastases. Previous therapies including dacarbazine and radiation of 39 Gy to the esophageal region were performed, but the liver metastases deteriorated. The patient was then administered nivolumab (2âmg/kg, every 3 weeks). After 3 cycles, the esophageal tumor and lymph nodes showed marked reductions in size, the lung metastases disappeared, and the liver metastases shrank partially. The treatment continued with 7 cycles for 4 months. However, severe anemia and thrombocytopenia appeared in the 6th cycle, and intermittent blood transfusions were required. The patient received high-dose intravenous methylprednisolone therapy for bi-cytopenia, but it was ineffective. Seven months after the initiation of nivolumab, the patient died of tumor. Although the mechanisms of bi-cytopenia were unclear, it could have been induced by nivolumab. CONCLUSION: The present case shows a rare but serious life-threatening bi-cytopenia possibly associated with nivolumab and suggests the importance of awareness of hematological adverse events during nivolumab therapy.

A 75-year-old man diagnosed with ileal gastrointestinal tumor with peritoneal dissemination was subjected to salvage treatment with regorafenib at 120 mg/day. Following the initiation of the treatment, liver dysfunction appeared on day 28, and continued to worsen despite termination of the treatment. Since no increase in the levels of serum immunoglobulins of the patient was observed, and negative results were obtained for the analysis of viral markers and autoantibodies, a diagnosis of regorafenib-induced hepatitis was suggested. In consequence, the patient received steroid pulse therapy and continuous administration of prednisolone, without sufficient improvement. Liver biopsy revealed interface hepatitis with prominent plasma cell infiltration, suggesting regorafenib-induced autoimmune hepatitis. The patient was then administered azathioprine and prednisolone, which improved the hepatic injury. The present case represents the first report of successful treatment of regorafenib-induced severe hepatic injury by the use of an immunosuppressant.
RESUMO
In 2013, a 76-year-old male with a cardiac pacemaker was diagnosed with adenosquamous carcinoma of the duodenum. Subsequently, a pancreatoduodenectomy and lymph node dissection were performed, and 12 cycles of adjuvant chemotherapy (modified FOLFOX6 regimen), which consisted of fluorouracil, leucovorin and oxaliplatin, were administered via a central venous catheter. At 5 months after the completion of adjuvant chemotherapy, the patient experienced the sudden onset of severe pain at the back right of the ear, edema of the right side of the face and right jugular vein dilatation. Computed tomography (CT) revealed filling defects in the superior vena cava (SVC) and right brachiocephalic vein, indicating catheter-induced venous thrombosis. Although the catheter was removed and anti-coagulation therapy, aspiration of the thrombosis and ballooning dilatation were performed immediately, the patient's symptoms were not ameliorated. Notably, histological examination following thrombus aspiration revealed metastatic cancer cells, and fluorodeoxyglucose-positron emission tomography/CT identified metabolically active nodules in the SVC at locations consistent with the initial duodenal tumors detected by CT and in the first thoracic vertebrae. The tumor thrombus rapidly increased in size and resulted in worsening dyspnea. Subsequently, radiotherapy was performed, followed by chemotherapy, which relieved the systemic symptoms and suppressed the tumor growth. Adenosquamous carcinoma of the duodenum is extremely rare, and to the best of our knowledge, intraluminal SVC metastasis as a result of adenosquamous carcinoma of the duodenum has not been reported previously. The placement of a cardiac pacemaker, central venous catheter and tumor cells possessing high metastatic potential are hypothesized to have contributed to this rare case of metastasis.
RESUMO
BACKGROUND: Metastatic renal cell carcinoma (mRCC) had been a chemo-refractory disease, but recent advances in multiple kinase inhibitors such as sunitinib have dramatically changed the clinical course of mRCC. Sunitinib is used for mRCC chemotherapy based on the favorable results of a recent clinical trial, but specific biomarkers predicting efficacy and safety are not yet available. Locally advanced bile duct carcinoma (BDC) has generally been treated with single agent gemcitabine or as doublet therapy with cisplatin. Concomitant occurrence of mRCC and BDC is extremely rare, and a standard therapeutic strategy has not been established. CASE PRESENTATION: A 65-year-old woman was diagnosed as having multiple mRCC and intercurrent, locally advanced BDC. A single course of combination therapy with sunitinib (25 mg/day, day2-15) and gemcitabine (750 mg/m(2), days 1, 8) was administered, and this showed obvious effects, with partial response for mRCC and stable disease for BDC. However, the patient also experienced severe adverse events, including hematological and various non-hematological toxicities; the combination therapy was then terminated on day 13 after its initiation. She recovered on day 28 and is alive 3.5 years after the diagnosis. The plasma trough levels of sunitinib and its active metabolite SU12662 on day 13 were 91.5 ng/mL and 19.2 ng/mL, respectively, which were relatively higher than in previous reports. Analysis of her single nucleotide polymorphisms (SNPs) detected TC in ABCB1 3435C/T, TC in 1236C/T and TT in 2677G/T, suggesting a possible TTT haplotype. CONCLUSION: A rare case of double cancer of mRCC and BDC was treated by combination chemotherapy. Although unknown synergistic mechanisms of these agents may be involved, severe toxicities might be possibly associated with high sunitinib exposure. Further exploration of combination therapy with sunitinib and gemcitabine is required.

A 64-year-old male presented with increased abdo-minal fullness and fever. Radiological examination revealed moderate ascites, a tumor with a diameter of 12.5 cm in the mesenteric region, as well as multiple tumors in the thoracic and abdominal para-aortic regions and in the left supraclavicular regions. Pathohistological findings of the biopsy specimen revealed atypical spindle cells accompanied by infiltration of lymphocytes. The plasmacytes were positive for CD68, murine double minute 2 and S-100, while they were negative for α-smooth muscle actin, cyclin-dependent kinase 4 and anaplastic lymphoma kinase. Clinically, the patient presented systemic symptoms and laboratory results indicated an elevation in the inflammatory response, while the CT and MRI findings were consistent with an inflammatory myofibroblastic tumor (IMT). Based on the clinical and histological findings, the patient was diagnosed with IMT. In total, 4 cycles of combination chemotherapy with doxorubicin and ifosfamide were administered. Tumor size reduction by 50% was achieved subsequent to the 4th chemotherapy cycle. In conclusion, successful control of this rare metastatic IMT was achieved by systemic chemotherapy.
RESUMO
BACKGROUND: Retroperitoneal sarcomas (RPS), such as pleomorphic leiomyosarcoma, often invade or displace vital organs in the abdominal cavity and exhibit an aggressive clinical course. Complete surgical resection of the tumor and preoperative radiotherapy and chemotherapies can be used for non-metastatic RPS. However, in case of huge retroperitoneal sarcoma fully occupying the abdominal cavity, surgical resection tends to be insufficient, resulting in poor outcomes. This report describes a case of rapidly progressive retroperitoneal pleomorphic leiomyosarcoma that was favorably controlled by debulking surgery followed by combination chemotherapy and radiotherapy. CASE PRESENTATION: A 65-year-old Japanese woman developed abdominal discomfort due to a huge retroperitoneal tumor fully occupying the abdominal cavity. The immunohistochemical diagnosis was pleomorphic leiomyosarcoma with high-grade malignancy and aggressive proliferative features. Debulking surgery could be performed, but the small residual tumor had rapidly grown to an approximately 22 cm in length on the major axis within 38 days after the operation. The patient's general condition progressively declined. Combination chemotherapy, consisting of doxorubicin and ifosfamide, was successfully administered for six cycles while maintaining dose intensity. The best objective response was a partial response, and the chemotherapy was well tolerated. Approximately 50 Gy of radiotherapy was delivered to the remaining tumor. This multimodal strategy resulted in progression-free survival for more than 17 months and achieved sustained symptomatic relief. CONCLUSIONS: Multimodal therapy with debulking surgery, combination chemotherapy and radiotherapy controlled a rapidly progressive retroperitoneal pleomorphic leiomyosarcoma. Maintaining dose intensity of the chemotherapy and radiotherapy might contribute to overall tumor control.
