1/24. Anti-Yo positive paraneoplastic cerebellar degeneration associated with ovarian carcinoma: case report and review of the literature.paraneoplastic cerebellar degeneration (PCD) is a rare nonmetastatic neurological complication in cancer patients. Anti-Yo is one of the anti-onconeural antibodies found in PCD patients. It is believed that anti-Yo occurs almost always in women and is most likely associated with gynecologic or breast cancers, although exceptions exist. Here we report a PCD patient with ovarian cancer having high-titer anti-Yo. The acute onset of her PCD symptoms mimicked that of a stroke. Her ovarian cancer tissue contained abundant plasma cells and lymphocytes. After a thorough review of the literature, we propose a schematic hypothesis for the autoimmune pathogenesis of PCD. Despite anecdotal case reports of neurological improvement with different combinations of treatment, including IVIg, there is still no definitely effective treatment for PCD. Further research on the pathogenesis of PCD may lead to more effective therapies.- - - - - - - - - - ranking = 1keywords = cancer (Clic here for more details about this article) |
2/24. Anti-Ri-associated paraneoplastic cerebellar degeneration without opsoclonus in a patient with a neuroendocrine carcinoma of the stomach.We report a case of a 63-year-old man suffering from anti-Ri-associated paraneoplastic cerebellar degeneration (PCD) with gastric cancer. The neurologic presentation was limited to severe cerebellar ataxia without opsoclonus. The gastric cancer was composed of both poorly differentiated adenocarcinoma and neuro-endocrine carcinoma. The patient's serum reacted with recombinant Ri antigen and the neuroendocrine tumor component. It is thus considered that PCD without opsoclonus in the present case was related to the gastric neuroendocrine tumor and anti-Ri antibody.- - - - - - - - - - ranking = 0.5keywords = cancer (Clic here for more details about this article) |
3/24. paraneoplastic cerebellar degeneration as the first evidence of cancer: a case report.paraneoplastic cerebellar degeneration (PCD) is the most frequently seen paraneoplastic syndrome affecting the brain. PCD is most commonly associated with cancers of the ovary, breast, and lung. The anti-Purkinje cell antibodies (anti-Yo) that specifically damage the purkinje cells of the cerebellum are found in the patient's serum and cerebrospinal fluid. The typical presentation of PCD includes limb and truncal ataxia, often along with dysarthria. This report describes the case of a 47-year-old woman without significant medical history who developed new onset of unsteady gait, headache, and vertigo. The imaging studies suggested rhombencephalitis. The patient initially responded to corticosteroid treatment. Unfortunately, her gait ataxia worsened and she developed dysarthria, neither of which responded to increasing dosages of corticosteroids. Extensive imaging studies showed no evidence of tumor, but the patient was found to have positive anti-Yo antibodies and elevated cancer antigen 125 (CA-125). pathology results from exploratory laparotomy revealed stage III C adenocarcinoma of the ovary. This case demonstrates that PCD may be the presenting symptom of an occult malignancy. The pathogenesis, diagnosis, and treatment of PCD, and its rehabilitation implications, are reviewed.- - - - - - - - - - ranking = 1.5keywords = cancer (Clic here for more details about this article) |
4/24. Successful immunosuppressant therapy of severe progressive cerebellar degeneration and sensory neuropathy: a case report.A 56 year old woman had a 19 month history of a severe subacute progressive cerebellar degeneration, peripheral sensory neuropathy, and urinary incontinence. She was confined to a wheelchair, needed assistance with eating, and her speech was almost unintelligible. No underlying cancer was found despite repeated investigations, and no autoantibodies were demonstrated. She received a 3-month course of intensive immunosuppressant therapy with intravenous immunoglobulin 400 mg/kg per day for 5 days every month, oral cyclophosphamide 50 mg twice or three times a day to maintain the total lymphocyte count between 500 and 750/mm(3), and prednisone 60 mg per day. She experienced dramatic subjective and objective improvement. The dysarthria and the upper extremity dysmetria disappeared, and she regained the ability to write and cook. The lower extremity ataxia improved and she became able to walk with a cane. urinary incontinence disappeared. A trial of intensive immunosuppressant treatment is worth considering in a patient with a clinical syndrome resembling paraneoplastic disorders, even if an underlying neoplasm and autoantibodies are not demonstrated.- - - - - - - - - - ranking = 0.25keywords = cancer (Clic here for more details about this article) |
5/24. Two paraneoplastic syndromes in a patient with ovarian cancer: nephrotic syndrome and paraneoplastic cerebellar degeneration.BACKGROUND: A paraneoplastic syndrome-a rare, indirect system disturbance located distant from a neoplasm-has been reported in association with ovarian cancer. CASE: Two paraneoplastic syndromes-nephrotic syndrome and paraneoplastic cerebellar degeneration (PCD)-developed in a patient who had no symptoms from ovarian cancer. She presented with the nephrotic syndrome. Evaluation for metastasis, including computed tomography (CT) scan and ultrasonography, showed a slightly enlarged right ovary and a 2-cm lower paraaortic lymph node on the right side. A 5-cm ovarian mass and multiple paraaortic lymph nodes were excised, and six cycles of carboplatin and paclitaxel were given. nephrotic syndrome symptoms had greatly subsided at 6 weeks after surgery. At 7 months after surgery, symptoms of PCD developed yet CT, CA-125 levels, and physical examination showed no evidence of ovarian cancer. CONCLUSION: To our knowledge, development of two paraneoplastic syndromes in one patient with ovarian cancer has not been reported. nephrotic syndrome resolved with treatment of the neoplasm whereas PCD did not.- - - - - - - - - - ranking = 2keywords = cancer (Clic here for more details about this article) |
6/24. Anti-Yo-associated paraneoplastic cerebellar degeneration in a man with gastric adenocarcinoma.paraneoplastic cerebellar degeneration (PCD) with anti-Yo antibodies is almost always associated with ovarian and breast cancer. We describe a man with anti-Yo-positive PCD and gastric adenocarcinoma. The tumor cells were labeled with anti-Yo antibodies by immunohistochemistry. High serum titers of anti-Yo antibodies were found before surgery and decreased 6 months after resection of the tumor. The expression of Yo antigens by the tumor and the decrease in anti-Yo antibody titers after its removal suggest that the immune response against the purkinje cells of the cerebellum was triggered by the tumor.- - - - - - - - - - ranking = 0.25keywords = cancer (Clic here for more details about this article) |
7/24. paraneoplastic cerebellar degeneration as the first manifestation of cancer.paraneoplastic cerebellar degeneration (PCD) is a type of paraneoplastic syndrome that primarily affects women with gynecological cancers. patients typically experience pancerebellar symptoms, including gait ataxia, dysarthria, nystagmus, and truncal and appendicular ataxia. We present the case of a 50-year-old woman with PCD and presumed ovarian cancer who initially complained of ataxia and dysarthria. PCD was diagnosed on the basis of her symptoms, diagnostic imaging, and laboratory work. PCD symptoms may precede the diagnosis of malignancy by months or years. early diagnosis and treatment of these syndromes, including rehabilitation, may result in improvements in quality of life for this population of patients.- - - - - - - - - - ranking = 1.5keywords = cancer (Clic here for more details about this article) |
8/24. paraneoplastic cerebellar degeneration: neurological symptoms pointing to occult ovarian cancer.paraneoplastic cerebellar degeneration with anti-Yo antibodies is a rare but disabling neurodegenerative disease that may point to an occult ovarian cancer. Symptoms usually accompanying paraneoplastic cerebellar degeneration include truncal and limb ataxia, dysarthria, dysphagia, nystagmus, vertigo, and diplopia. The pathogenesis of paraneoplastic neurological syndromes is unknown. Treatment results of the neurological symptoms are disappointing. The present case illustrates how neurological symptoms pointed to an occult ovarian cancer.- - - - - - - - - - ranking = 1.5keywords = cancer (Clic here for more details about this article) |
9/24. paraneoplastic syndromes associated with lung cancer: a unique case of concomitant subacute cerebellar degeneration and lambert-eaton myasthenic syndrome.IMPLICATIONS: We report an unusual case in which a patient with paraneoplastic subacute cerebellar degeneration (a brain disorder resulting from antibody production by a tumor located outside the skull) developed lambert-eaton myasthenic syndrome (antibody-mediated skeletal muscle weakness) that was not apparent until she underwent surgery. Failure to recognize this disease process can cause life-threatening respiratory distress.- - - - - - - - - - ranking = 1keywords = cancer (Clic here for more details about this article) |
10/24. A case of paraneoplastic syndrome accompanied by two types of cancer.A case of paraneoplastic syndrome accompanied by two types of cancer is reported. The patient was a 62 year old man who progressively developed cerebellar ataxia, especially an abnormal gait. The anti-Hu antibody titre was high. A small tumour was detected in the middle lobe of the right lung and was surgically treated. The histology was adenocarcinoma. After lobectomy, however, the ataxia deteriorated, and plasma exchange, 250 ml/kg/day, was conducted for 6 days. After plasma exchange, the anti-Hu antibody titre decreased and the ataxia temporarily ceased to progress. A week after the last plasma exchange, a mass appeared in the anterior cervical region and rapidly increased in size. The biopsy of the neck tumour disclosed a small cell carcinoma. Five months later small cell carcinoma appeared in the left lung. This case shows the importance of searching for small cell carcinoma when anti-Hu antibodies are detected. It is assumed that plasma exchange removed not only a pathogenic factor of ataxia but also a factor which inhibited the growth of the small cell carcinoma. It is recommended that plasmapheresis should be performed with caution in paraneoplastic syndrome when the origin of a tumour is obscure.- - - - - - - - - - ranking = 1.25keywords = cancer (Clic here for more details about this article) |
