| 1 | Metastatic clear cell renal cell carcinoma in isolated retroperitoneal lymph node without evidence of primary tumor in kidneys: A case report显示文摘BACKGROUND Retroperitoneal lymph node dissection(RPLND)plays a diagnostic,therapeutic,and prognostic role in myriad urologic malignancies,including testicular carcinoma,renal cell carcinoma(RCC),and upper urinary tract urothelial carcinoma.RCC represents 2%of all cancers with approximately 25%of patients presenting with advanced disease.Clear cell RCC(CCRCC)is the most common RCC,accounting for 75%-80%of all RCC.CASE SUMMARY A 71-year-old man presented with a history of benign prostatic hypertrophy.He was asymptomatic without any hematuria,pain,or other urinary symptoms.A computed tomography(CT)scan of the abdomen and pelvis showed a 1.8 cm left retroperitoneal lymph node.There was no evidence of renal pathology.A core biopsy was performed of the left para-aortic lymph node.Although the primary tumor site was unknown,the morphological and immunohistochemical features were most consistent with CCRCC.A RPLND was performed which revealed a single mass 5.5 cm in greatest dimension with extensive necrosis.The retroperitoneal lymph node was most compatible with CCRCC.A nephrectomy was not conducted as a renal mass had not been detected on any prior imaging studies.The patient did not receive any type of adjuvant therapy.The patient underwent surveillance with serial CT scans with contrast of the chest,abdomen,and pelvis for the next 5 years,all of which demonstrated no recurrent or metastatic disease and no evidence of retroperitoneal adenopathy.CONCLUSION Our unique case emphasizes the therapeutic role of metastasectomy in metastatic CCRCC even in the absence of primary tumor in the kidneys. | Lisa BE Shields Arash Rezazadeh Kalebasty | 2020 | World Journal of Clinical Oncology2020，11，2： | 1 |
| 2 | Concurrent renal cell carcinoma and hematologic malignancies: Nine case reports显示文摘BACKGROUND The presence of renal cell carcinoma(RCC)and hematologic malignancies(HM)in the same patient is rarely observed.Three primary findings have been described in these patients,including male gender and lymphoid malignancy predominance,and the HM are usually diagnosed before or simultaneously with the RCC.There is a lack of evidence about clinical outcomes in this setting.We report the common characteristics of 9 patients diagnosed with concurrent RCC and HM and their clinical course and response to treatment.CASE SUMMARY Four(44%)patients were diagnosed with RCC prior to the HM,the diagnosis was simultaneous in 4(44%)patients,and 1(11%)patient was diagnosed with the HM prior to the RCC.No patients were treated with cytotoxic chemotherapy or radiation between the diagnosis of RCC and HM.Several unique features were seen in our case series,such as 3 simultaneous cancers in 1(11%)patient,a splenectomy leading to remission of diffuse large B cell lymphoma without the use of chemotherapy in 1(11%)patient,chemotherapy and rituximab for lymphoma resulting in a complete response in primary RCC in 1(11%)patient,and immunotherapy providing an excellent response for primary renal leiomyosarcoma in 1(11%)patient.CONCLUSION These findings highlight the potential role of immune system dysregulation in patients with the diagnosis of RCC and HM whereby the first malignancy predisposes to the second through an immunomodulatory effect.HM have the potential of being confused with lymph node metastasis from kidney cancer.Lymph node biopsy may be necessary at the time of initial diagnosis or in cases of mixed response to therapy.Long-term medical surveillance is warranted when a patient is diagnosed with RCC or HM.Clinicians should be aware of the higher prevalence of male gender and lymphoid malignancy with concurrent RCC and HM and that either of these conditions may be diagnosed first or they may be diagnosed simultaneously. | Lisa BE Shields Arash Rezazadeh Kalebasty | 2020 | World Journal of Clinical Oncology2020，11，8： | 1 |
