Because intracranial germinomas are readily curable with radiation and chemotherapy or radiation therapy alone, the role of radical surgery has become debatable. This study assesses the optimum degree of surgical resection for intracranial germinomas. Twenty-nine patients who underwent surgery for germinoma were retrospectively analyzed (male/female ratio 27:2, median age 18 years). Among these 29 patients there were 10 solitary pineal, seven solitary
neurohypophyseal
/hypothalamic, and 12 multifocal or disseminated tumors. Biopsy samples were obtained in 16 patients (stereotactically in eight, transsphenoidally in four, and via frontotemporal craniotomy in four). Partial resection was attained in five patients (via a frontotemporal approach in three and occipitotranstentorially in two). Gross-total resection was achieved via an occipitotranstentorial route in eight patients with pineal masses. After surgery, 10 patients were treated with radiotherapy alone, and 19 received radiation and chemotherapy; complete remission was achieved in all 29 patients. The overall tumor-free survival rate was 100% at a median follow-up period of 42 months. There was no significant difference in outcome related to the extent of surgical resection. Postoperative neurological improvement was seen in only two patients, whereas transient postoperative complications, mainly upgaze palsy, were observed in six. One patient experienced a slight
hemiparesis
, bringing the surgical morbidity rate to 3% (one of 29). It is concluded that radical resection of intracranial germinomas offers no benefit over biopsy. The primary goal of surgery should be to obtain a sufficient volume of tumor tissue for histological examination. If there is strong evidence of germinoma on radiological studies, biopsy samples should be obtained. When a perioperative histological diagnosis of pure germinoma is made during craniotomy, no risk should be taken in continuing the resection.

Ultrasonography revealed a suprasellar tumor in a fetus at 28 weeks of gestation. The male newborn, delivered 10 weeks later, was operated at the age of 17 days, and a craniopharyngioma was completely removed. Intraoperatively, inappropriate secretion of
antidiuretic hormone
occurred and was followed by diabetes insipidus causing imbalance of fluid and electrolytes. The tumor recurred and was totally removed 1 year later. Further development was uneventful and, at the age of 8 years, the boy is in generally good mental and physical condition except for a left-sided
hemiparesis
. In contrast to the poor outcome of neonatal craniopharyngioma reviewed in the literature, this case may encourage radical surgery even in the very young.

Long-term posttreatment Karnofsky Performance Status (KPS) and neurological status of 16 patients with
neurohypophyseal
(NH) germinomas were retrospectively analysed, in order to deduce the best treatment modality to achieve a good outcome. The average age at treatment was 15.5 years (rouge 6-26) and they were followed up for 107.3 months (26-209). The KPS averaged 81.5 (0-100). Three patients were below 60 in the KPS. The first one had
hemiparesis
due to a delayed cerebrovascular accident (CVA), and the second became indifferent and inactive with recent memory loss. The third died from marginal recurrence of tumour and subsequent systemic metastasis. The low scores were all more or less attributable to complications related to irradiation: delayed CVA, diffuse cortical atrophy and inappropriate selection of irradiation field, respectively. The second case had the tumour origin at the hypothalamus, which indicates intraparenchymal tumour location as another factor to worsen the quality of life (QOL). Visual field and acuity, and EOM impairment were observed in eight and five patients, respectively. It improved in all patients but one. The visual and EOM dysfunction recovered satisfactorily and was not a disabling factor. The intraparenchymal lesion resulting in
hemiparesis
and higher cortical dysfunction due to either irradiation-related complications or tumour invasion is a major determining factor of lower KPS. Irradiation related complications are considered to be avoidable by reducing radiation dosage with appropriate chemotherapy and/or proper selection of irradiation field. Patients with smaller tumour size of less than 20 mm had higher KPS. Accordingly, repeated studies of tumour markers and neuroimages are required in patients with idiopathic diabetes insipidis, in order to detect the tumour, if present, at the small-sized and early stage.

Non-small cell lung cancer with syndrome of inappropriate secretion of
antidiuretic hormone
(SIADH) is rare. A case of squamous bronchogenic carcinoma with SIADH is reported. A 64-year-old man was admitted with 2 cm nodule of the left lung on chest radiography. Transbronchial lung biopsy revealed the squamous cell carcinoma. His past history included hypertension and
hemiparesis
due to brain infarction. Serum sodium level was low (122 mEq/l) and serum osmolarity was low (271 mOsm/kgH2O). However, urine sodium level was high (82 mEg/l) and urine osmolarity was high (461 mOsm/kgH2O). Renal and adrenal function was normal. He was diagnosed with cT1N0M0 squamous bronchogenic carcinoma accompanied by SIADH. He underwent left upper lobectomy with lymph node dissection. Five months after the operation, serum sodium level returned to normal. He remains well 20 months after the operation.
