Oxaliplatin-induced severe anaphylactic reactions in metastatic colorectal cancer: Case series analysis

AIM: To investigate oxaliplatin-induced severe anaphylactic reactions (SAR) in metastatic colorectal cancer in a retrospective case series analysis and to conduct a systemic literature review. METHODS: During a 6-year period from 2006 to 2011 at Kaohsiung Veterans General Hospital, a total of 412 patients exposed to oxaliplatin-related chemotherapy were retrospectively reviewed. Relevant Englishlanguage studies regarding life-threatening SAR following oxaliplatin were also reviewed in MEDLINE and PubMed search. RESULTS: Eight patients (1.9%, 8 of 412 cases) were identified. Seven patients were successful resuscitated without any sequelae and one patient expired. We changed the chemotherapy regimen in five patients and rechallenged oxaliplatin use in patient 3. Twenty-three relevant English-language studies with 66 patients were reported. Patients received a median of 10 cycles of oxaliplatin (range, 2 to 29). Most common symptoms were respiratory distress (60%), fever (55%), and hypotension (54%). Three fatal events were reported (4.5%). Eleven patients (16%) of the 66 cases were rechallenged by oxaliplatin. CONCLUSION: SAR must be considered in patients receiving oxaliplatin-related chemotherapy, especially in heavily pretreated patients. Further studies on the mechanism, predictors, preventive methods and management of oxaliplatin-related SAR are recommended.

Clinical characteristics and prognosis of traumatic basal ganglia hematomas: A retrospective analysis of 40 cases

AIM： To retrospectively analyze the pathogenesis, clinical characteristics, treatment and prognostic characteristics in patients with traumatic basal ganglia hematomas （TBGH）. METHODS： A retrospective analysis of the clinical data was performed in 40 patients with TBGH who were selected from 1 250 patients with closed brain injury, who admitted to the Department of Neurosurgery of Shangqiu First People＇s Hospital from January 1990 to January 2004. The pathogenesis, clinical characteristics and signs, results of radiological examination, treatment and prognostic characteristics were analyzed. The patients all had definite history of brain injury, manifested by neurological functional disturbance to different extent after brain injury, and basal ganglia hemorrhage was identified by CT after brain injury, and hemorrhagic volume were more than or equal to 2 mL. Totally 34 males and 6 females were enrolled, aged 16-72 years and 28 cases of them were younger than 40 years old. The prognosis of the patients was evaluated with Glasgow outcome scale （GOS） at 6 months after injury, and GOS scoring standard was 1-5 points （1 for dead; 2 for vegetative survival, long-term coma, manifestations of decorticate rigidity or decerebrate rigidity; 3 for severely disabled, should be look after by others; 4 for moderately disabled, be able in self-care; 5 for good recovery, adults can work and study）. RESULTS： The enrolled cases accounted for 3.20% of the 1250 patients with closed brain injury admitted at the same period. ① The causes of injury included traffic accident in 36 cases, fall in 2 cases, and assault in 2 cases. ②At admission, the Glasgow coma scale （GCS） scores were as follow： 13-15 scores （mild） in 10 cases, 9-12 scores （moderate） in 20 cases, and 3-8 scores （severe） in 10 cases. Hemiplegia presented in 37 cases, aphasia in 20 cases, conscious disturbance in 10 cases, unilateral mydriasis in 6 cases, and decerebrate rigidity in 2 cases. ③ TBGH was detected by CT within 30 minutes to 24 hours after injury in 37 cases, and delayed TBGH was diagnosed by serial CT reexamination at 24 to 48 hours after injury in 3 cases. Apart from the TBGH, signs of diffuse axonal injury （DAI） were observed in 22 cases and the criterion of CT diagnosis was that apart from TBGH, small hemorrhagic loci were found in the deep white matter of the hemisphere, corpus callosum, dorsolateral quadrants of the midbrain and the upper pons, internal capsule, basal ganglia area, intraventricle, and cerebellum, etc., but there was no obvious mass effect （clinically manifested by conscious disturbance immediately after brain injury, and primary coma lasted for longer than 6 hours）. Secondary intraventricular hemorrhage occurred in 19 cases, acute subdural hematoma in 3 cases, acute epidural hematoma in 1 case, cerebral contusion in 7 cases, and diffuse cerebral swelling in 3 cases. TBGH located at contralateral to the side of impact in 29 cases. The volume of TBGH was 3-9 mL in 8 cases, 10-19 mL in 10 cases, 20-29 mL in 12 cases, and more than 30 mL in 9 cases. ④Ten patients underwent surgical treatment, including TBGH were evacuated by craniotomy in 7 cases, drained by drilling hole in 2 cases, and hematoma drainage combined with extraventricular drainage in 1 case. 30 patients received conservative treatment, including hyperbaric oxygen treatment in 22 cases. ⑤At 6 months after injury, good recovery obtained in 10 cases （25%）, moderately disabled in 17 cases （42.5%）, severely disabled in 2 cases （5%） and dead in 11 cases （27.5%） respectively. CONCLUSION： In our study, the proportion of TBGH in closed brain injury was 3.2%, and it had a higher incidence of disability. Most of the patients were young people and injured in traffic accident, and TBGH mostly oc- curred at contralateral to the side of impact. The patients suffered from hemiplegia and long-term coma, incidence rate of diffuse axonal injury was higher, but conscious disturbance was milder. Conservative treatment was mainly applied in our study. CT scan can not only establish the position, volume of TBGH, but also establish if it combines with other intracranial injury, and it is helpful to detect delayed TBGH.

Focal nodular hyperplasia with concomitant hepatocellular carcinoma: a case report and clonal analysis

This report describes a hepatocellular carcinoma (HCC) with concomitant focal nodular hyperplasia (FNH) in a 56 years old Chinese man. There were two well circumscribed tumours measuring 3×2.5×2 cm and 2×1.5×1.5 cm. The larger mass was grey and soft with a small area of bleeding and necrosis and an intact capsule. The smaller mass was yellow and had no capsule. Clonal analysis was carried out to clarify the relation between the HCC and the adjacent FNH. The clonal analysis was based on the methylation pattern of the polymorphic X chromosome linked androgen receptor gene (HUMARA). In FNH, after Hpa Ⅱ digestion, the allelic bands showed two well defined peaks. The intensity of the two peaks in the DNA from cirrhotic tissue did not differ significantly, consistent with a random pattern of X chromosome inactivation. However, in HCC, after Hpa Ⅱ digestion, the allelic bands differed significantly in intensity. Therefore, there was a typical polyclonal pattern of inactivation in FNH but the HCC was interpreted as being monoclonal.

FEMALE LARYNGOCARCINOMA (CLINICAL ANALYSIS OF 267 CASES)

Two hundred and sixty-seven cases of female laryngocarcinoma, treated in our hospital in the past 33 years, were analysed. It is suggested that a relating preponderance of male sex hormonal influence after menopause should be a contributing factor responsible for the high prevalemce of laryngeal cancer in women. The other etiological factor was cigarette smoking. The pathological types and patterns of metastasis to cervical lymphnodes in the female laryngocarcinoma were similar to those observed in male patients but the superglottic cancer was more common than the flottic type. However, no significant difference in prognosis was observed between superglottic and glottic cancers. Provided indications are strictly adhered to, partial laryngectomy that can give therapeutic resulrs similar or even superior to total laryngocarcinoma.

PRIMARY PLASMA CELL LEUKEMIA(A COMPREHENSIVE ANALYSIS OF 44 CASES)

Four cases of primary plasma cell leukemia (PPCL) admitted to Zhongshan Hospital from 1959 to 1987 are reported with a review on additional 40 cases reported in China. Comparing with the 57 cases of multiple myeloma (MM) treated in our hospital, the following features were observed in PPCL: (1) The age was younger, with a mean of 45.2 years, 34.1% of the patients were under 40 years. (2) Onset was abrupt. Duration from onset to diagnosis was 2 months or less in 77% patients but never beyond 6 months. (3) 81.8% patients had liver enlargement, 59.1% splenomegaly and 61.4% sternum tenderness. (4) All patients showed marked anemia with an average hemoglobin of 65 g/L. BPC count was less than 100 × 109/L in 76% patients and WBC was more than 10×109/L in 77%. (5) Plasma cell number in the marrow was markedly increased with an average of 69%, of which the blast cells and immature forms were predominant. (6) No destruction of bones was shown on X-ray film in 68.3% patients. (7) The response to chemotherapy was poor with a total response rate of 18% and a mean survival of 2 months. All the above-mentioned clinical features were significantly different from those of MM. In addition, these two diseases were also different in cytology, cytogenetics and ultrastructure. Therefore, PPCL should be considered as a special type of acute leukemia distinct from MM. High dose of alkylating agents in combination with autologous bone marrow transplantation might improve the prognoses.
