[3D-Ct-planned interstitial HDR brachytherapy + percutaneous irradiation and chemotherapy in inoperable pancreatic carcinoma. Methods and clinical outcome].

PURPOSE: Clinical experiences in interstitial 192-iridium HDR brachytherapy for the treatment of unresectable pancreatic carcinoma are presented. Brachytherapy has been used as boost irradiation in a multimodality treatment concept together with external radiotherapy and simultaneous chemotherapy. Practicability during clinical routine, tolerability and toxicity of treatment are investigated. PATIENTS AND METHODS: Nineteen patients (9 female, 10 male, median age 67 years) with unresectable carcinoma of the pancreas have been treated with interstitial brachytherapy. Distribution according to UICC stages showed 4, 10 and 5 patients in stage II to IV respectively. In all cases afterloading technique with 192-iridium in HDR-modus was used. A total dose of 10 to 34 Gy to the reference isodose was delivered (single dose 1.88 to 5 Gy, median 2.5 Gy). Brachytherapy was followed by external radiotherapy, delivering an additional dose of 40 to 58 Gy. Nine patients received simultaneous chemotherapy (5-fluorouracil, leucovorin). Treatment planning was performed based on CT scans, allowing spatial correlation of isodose curves to the patient's anatomy. RESULTS: Median survival time was 6 months. A trend of lower survival rates with advanced stage of disease (median survival stage IV 4 months, stage II and III 6.5 months) was seen. Local control rate was 70%. Brachytherapy treatment was well tolerated, severe acute side effects were not observed. One patient developed pancreatic fistulae 4 months and 1 patient a gastric ulcer 7 months after treatment. Pain release was achieved in all patients. CONCLUSIONS: 192-iridium HDR-brachytherapy is an effective tool in the treatment of unresectable pancreatic carcinoma with a high rate of local control and a low rate of side effects and is comparable IORT or seed implantation.

Locoregional recurrence of breast cancer following mastectomy: always a fatal event? Results of univariate and multivariate analysis.

PURPOSE: The outcome of patients with local-regional breast cancer recurrence after mastectomy often is described as fatal. However, certain subgroups with favorable prognoses are thought to exist. To determine these favorable subgroups, we analyzed prognostic factors for their influence on postrecurrence survival by univariate and multivariate analysis. METHODS AND MATERIALS: Between 1979 and 1992, 145 patients with their first isolated locoregional recurrence of breast cancer following modified radical mastectomy without evidence of distant metastases were treated at the Department of Radiation Oncology of the University of Wurzburg. Thirty-nine percent of patients (n = 67) had had postmastectomy radiotherapy, representing 7% of patients who had received routine postmastectomy irradiation at our institution. Systemic adjuvant hormonal therapy had been applied in 24% and systemic chemotherapy in 19% of patients. Several combinations were used. Treatment of recurrences consisted of surgical tumor excision in 74%, megavoltage irradiation in 83%, additional hormonal therapy in 41%, and chemotherapy in 12% of patients, employing different combinations. Local control in the recurrent site was achieved in 86%. Median follow-up for patients alive at the time of analysis was 8.9 years after recurrence. We tested different prognostic factors, including prior treatment and treatment of recurrence, for their influence on postrecurrence survival, using univariate and multivariate analysis. RESULTS: Eighty-two of the 145 patients (57%) developed distant metastases within the follow-up period. Metastases-free rate was 42% at 2 years and 36% at 10 years following recurrence. With development of distant metastases, the survival rate deteriorated. Recurrences appeared within the first 2 years from primary surgery in 56% of patients, and in 89% within 5 years. Overall, 2-year and 5-year survival rates following local-regional recurrence were 67% and 42%, respectively. Univariate analysis revealed statistically significant worsening of survival rates for pT3 + 4 primary tumors, primary axillary lymph node involvement, tumor grading 3 + 4, lymphatic vessel invasion, blood vessel invasion, tumor necrosis, negative estrogen (ER) and progesterone (PR) hormonal receptor status, postmastectomy chemotherapy and hormonal therapy, short time to recurrence (< 1 year), combined recurrences and supraclavicular site of recurrence, non-scar recurrence, size of the largest recurrent nodule > 5 cm, multiple recurrent nodules, no surgical excision of recurrence, small target volume of irradiation, chemotherapy for recurrence, and no local control within the recurrence site. The 2-year and 5-year survival rates ranged from 68% to 94%, and from 33% to 65%, respectively, in the favorable subgroups compared to 2-year and 5-year survival rates ranging from 20% to 59% and 0% to 35%, respectively, in the unfavorable subgroups. Multivariate analysis showed that site of recurrence and number of recurrent nodules have the strongest influence on postrecurrence survival, but time to recurrence, age at time of recurrence, local control in recurrent site as well as primary pT and axillary status, and the presence of tumor necrosis in the primary tumor specimen showed additional independent influences on survival. Thus, we identified a highly favorable subgroup of patients with a single chest wall or axillary recurrent nodule (in a patient aged > 50 years), a disease-free interval of > or = 1 year, pT1-2N0 primary tumor, and without tumor necrosis, and whose recurrence is locally controlled. This group (12 patients) had 5- and 10-year survival rates of 100% and 69%, respectively. CONCLUSION: We conclude that locoregional recurrence of breast cancer following mastectomy is not always a sign of systemic disease. Our data support previous findings, that subgroups with favorable prognosis exist and they still have a chance for cure, demanding comprehensive local treatment. (ABSTR

[The locoregional recurrence of rectal carcinoma. A computed tomographic analysis and a target volume concept for adjuvant radiotherapy].

BACKGROUND: In the adjuvant postoperative radiotherapy of rectal carcinoma the knowledge of the predominant areas of recurrences is of major importance for the definition of the target volume. We analysed the pattern and locations of tumor recurrences in the CT scans of 155 patients and correlated the findings with the primary tumor location (above and below the peritoneal duplication) and the operating method (abdominoperineal extirpation, anterior resection. Hartmann procedure). PATIENTS AND METHOD: Hundred and fifty-five patients with the diagnosis of rectal carcinoma recurrences were treated in our institution between 1980 and 1995. To determine the extension of the recurrent tumor within the pelvic levels (presacral levels S1-S5, precoccygeal, pelvic floor level and perineal level) and the tumor infiltration of pelvic organs and muscles we analysed the pretherapeutic CT images. The lymph node recurrences were classified as: pararectal, presacral, iliac internal, iliac external, iliac communis and para-aortal recurrences. RESULTS: Sixty-one percent of the patients with rectum extirpation and 66% with anterior resection showed a combined local and nodal recurrence. Isolated lymph node recurrences were rare (4% and 5%) (Tables 2 and 3). The local recurrence was mostly situated in the presacral pelvis, predominantly there was an infiltration of the presacral space at the level of S4, S5 and os coccygis regardless of the operating method and the primary tumor location (Figure 1). The anastomosis was involved in the tumor recurrence in 93% of the anteriorly resected patients (Table 3). In 9 out of 96 patients after rectum extirpation the pelvic region caudal of the tip of the coccyx was the origin of the recurrent tumor (Table 2, Figure 2). Primarily all 9 patients had a deep-seated carcinoma (< 6 cm ab ano). Only 2 patients showed an isolated perineal recurrence after rectum extirpation (Table 2. Figure 2). Two thirds of the deep-seated tumors showed a vaginal involvement (Figures 3 and 4). The incidence of iliac internal and presacral nodal recurrence was 47 to 59% (Figures 3 and 4). The incidence of iliac external lymph node recurrences was 7% after rectum extirpation and 2% after anterior resection/Hartmann procedure. CONCLUSION: Our data demonstrate that 2/3 of the patients with tumor-bed recurrences also show lymph node recurrences predominantly in the iliac internal and presacral groups. This has to be considered in the definition of the boost target volume. The target volume must also include the dorsal wall of the urogenital organs. A ventral extension of target volume up to iliac external lymph nodes is not necessary.

Three dimensional variability in patient positioning using bite block immobilization in 3D-conformal radiation treatment for ENT-tumors.

BACKGROUND AND PURPOSE: The aim of this prospective study was to analyze the three-dimensional (3D) reproducibility of the isocenter position and of patient positioning with the use of bite block immobilization by means of a simple verification procedure for a complex beam arrangement applied for ENT-tumors. MATERIALS AND METHODS: We analyzed the positioning data of 29 consecutive patients treated for ENT-tumors at the Department of Radiotherapy and Oncology of the University of Wurzburg. A total of 136 treatment sessions were analyzed. Patients were positioned and immobilized using an individualized bite block system and a head and neck support. A complex beam arrangement was applied combining two offset rotational and two oblique wedge fields on a 5 MV linear accelerator. Orthogonal verification films were taken once weekly. Four to six film pairs per patient were obtained (during 4-6 weeks) with a mean number of 4.7 film pairs per patient. These were compared to the corresponding orthogonal simulator films taken during primary simulation. Deviations of the verified isocenter from the isocenter on the simulator film were measured and analyzed in three dimensions in terms of overall, systematic and random categories. A 3D-deviation vector was calculated from these 3D data as well as a 2D-deviation vector (for comparison with literature data) from the lateral verification films. RESULTS: The overall setup deviation showed standard deviations (SD) of 2.5, 2.7 and 3.1 mm along the cranio-caudal, anterior-posterior and medio-lateral axes, respectively. The random component ranged from SD 1.9 to 2.1 mm and the systematic component ranged from SD 1.8 to 2.2 mm. The mean length of the 3D-vector was 3.1 mm for the systematic as well as the random component. Ninety percent of 3D systematic and random deviations were less than 5 mm. The mean length of the 2D-vector was 2.4 mm for the random component and 2.2 mm for the systematic component. Ninety percent of 2D-random and systematic variations were less than 4 mm. CONCLUSIONS: The presented individualized bite block immobilization device provides an accurate and reproducible patient positioning for 3D-conformal radiation therapy in the head and neck. Random and systematic deviations in each of the three directions are in the range of +/-4 mm (2 SD, comprising 95% of the deviations) and are within the range or even less than deviations described for most thermoplastic or PVC-mask fixation devices. These deviations should be taken into account during definition of planning target volume in head and neck tumors.

CT simulation in stereotactic brain radiotherapy--analysis of isocenter reproducibility with mask fixation.

BACKGROUND AND PURPOSE: CT verification and measurement of isocenter deviation using repeated mask fixation in linac-based stereotactic high dose radiotherapy of brain metastases were performed in this study. MATERIALS AND METHODS: For stereotactic radiotherapy of brain metastases a commercial head mask fixation device based on thermoplastic materials (BrainLAB) was used. A two-step planning-treatment procedure was performed. Immediately before treatment the patient was relocated in the mask and a verification CT scan of the radiopaque marked isocenter was performed and if necessary its position was corrected. The verification procedure is described in detail. Twenty-two CT verifications in 16 patients were analyzed. Deviations were measured separately for each direction. A 3D-deviation vector was calculated. Additionally the average amount of deviation in each of the three dimensions was calculated. RESULTS: The mean deviation and standard deviation (SD) of the isocenter was 0.4 mm (SD 1.5 mm) in the longitudinal direction, -0.1 mm (SD 1.8 mm) in the lateral direction and 0.1 mm (SD 1.2 mm) in the anterior-posterior direction. The mean three-dimensional distance (3D-vector) between the verified and the corrected isocenter was 2.4 mm (SD 1.3 mm). The average deviation (without consideration of direction) was 1.1 mm (SD 1.1 mm), 1.3 mm (SD 1.3 mm) and 0.8 mm (SD 0.9 mm) in the longitudinal, lateral and sagittal directions, respectively. No correlation was found between 3D-deviation and the distance of the isocenter from the reference plane nor between deviation and the position of metastases in the brain (central versus peripheral or between different lobes), or the date of treatment. CONCLUSION: Reproducibility of the isocenter using the presented mask fixation is in the range of positioning reproducibility reported for other non-invasive fixation devices for stereotactic brain treatment. Our results underline the importance of CT verification as a quality assurance method in stereotactic radiotherapy. Under the condition of a preceding CT verification the mask can be used for single dose stereotactic radiotherapy. For fractionated stereotactic irradiation of small target volumes we recommend repeated CT verifications to assure reproducibility.

Reflux, stricture and glomerular filtration rate after two antireflux techniques in continent urinary reconstruction using the right colon.

In the present study the incidence of reflux, stricture formation and changes in glomerular filtration rate in patients with the submucosal tunnel or the Camey-Le Duc technique of ureteric implantation into the caecum/detubularized right colon used for continent cutaneous diversion/orthotopic bladder substitution was investigated. Reflux was found in two renal units and ureterointestinal stenosis occurred in five renal units after submucosal tunnel ureteric implantation. After Camey-Le Duc ureteric implantation, one renal unit showed reflux and none had stenosis of the ureterointestinal anastomosis during follow-up. Mean glomerular filtration rate (ml/min/1.73 m2) fell from 98 to 85 in the submucosal tunnel group and from 88 to 81 in the Camey-Le Duc group after mean follow-ups of 9 and 5 years, respectively. Both methods of ureteric implantation in this study were effective in preventing reflux, and renal function was well preserved in both groups. The absence of ureterointestinal strictures in the Camey-Le Duc group is encouraging and indicates that this is a reliable method for reflux prevention.

[Bone metastasis in breast carcinoma].

113278891978 and 1988 278 patients with metastatic disease of breast cancer were treated at the Clinic of Radiotherapy of the University of Würzburg. 192 of these patients developed skeletal metastases. Particularly the skeletal axis was affected. In 58.3 percent (162 patients) skeletal metastasis was the first metastasis. The median age of the patients was 62.5 years at time of diagnosis of skeletal metastasis. Median interval between primary diagnosis of breast cancer and diagnosis of skeletal metastasis was 2.9 years. Median survival of patients with skeletal metastasis was 1.7 years. Skeletal metastases could not worse survival time, if other metastases already existed. Because of the relatively good prognosis we have to improve and combine the local and systemic therapy.

[Systematic analysis of local growth behavior and cervical lymph node metastasis of nasopharyngeal carcinoma--a clinical and computerized tomography examination].

BACKGROUND: Assessment of the incidence and patterns of cervical lymph node involvement according to the location, extension, and histological subtype of nasopharyngeal carcinoma. PATIENTS AND METHODS: The findings of the clinical and CT examinations of 80 patients with histological evidence of nasopharyngeal carcinoma (9T1-, 20 T2-, 17 T3-, 34 T4-carcinomas, lymph node involvement in 59 cases) were evaluated retrospectively. The histological subtype, local tumor spread, relation of the primary to the parapharyngeal fascias, compartments, and skull base structures were analysed and related to the cervical lymph node involvement. RESULTS: Two main types of nasopharyngeal carcinomas with different patterns of cervical lymph node involvement were identified: the posterior wall type, which spreads into the retropharyngeal and spinal accessorial neck node chains and the ventral type, which is located which is located at the roof, anterior, and lateral walls of the nasopharynx and spreads into the jugular neck node chains, preferring the neck side in which the main part of the primary is located. The border of lymph drainage via retropharyngeal-spinal accessorial or via jugular neck node chains is localised ventral of the origin of the m. capitus longus at the skull base. If the primary involves the prestyloidal compartment, the tumor may spread into the ipsilateral submaxillary lymph nodes. Combinations of the different types are frequently found with the neck node spread following the described directions. CONCLUSIONS: Knowledge of the regular patterns of spread of nasopharyngeal carcinoma is important for treatment procedures, especially for planning 3-dimensional radiotherapy.

Renal function up to 16 years after conduit (refluxing or anti-reflux anastomosis) or continent urinary diversion. 2. Renal scarring and location of bacteriuria.

OBJECTIVE: To evaluate the importance of refluxing versus anti-reflux ureteric implantation for the development of renal scarring in patients with a conduit or continent urinary diversion and for the incidence of bacteriuria in the upper urinary tract of patients with a conduit. PATIENTS AND METHODS: Renal scintigraphy using 99mTc-dimercaptosuccinic acid was performed on 32 of 37 evaluable patients from a prospective, randomized study at a mean of 150 months (range 102-198) after urinary diversion. In five patients with a conduit diversion and unilateral renal scarring, urine was samples for culture from the proximal end of the conduit and from both renal pelvices by direct percutaneous aspiration. RESULTS: Of 35 renal units (18 patients), studied after conduit diversion, scarring was found in 11 (two grade I, six grade II and three grade III) of 17 with refluxing anastomosis and in six (one grade I, four grade II and one grade III) of 18 with anti-reflux anastomosis (P = 0.06). Of 25 renal units (14 patients) after continent diversion, 16 showed scarring (seven grade I and nine grade II). Bacteriuria was found in four of five upper urinary tracts with a refluxing anastomosis, but in only one of five with an anti-reflux anastomosis. In these five patients scarring was present in all kidneys with refluxing anastomosis. CONCLUSION: Anti-reflux ureteric anastomosis seems to be important for preventing scarring and bacteriuria in the upper urinary tract of patients with a conduit urinary diversion. Despite the anti-reflux technique of ureteric implantation, most patients with a continent reservoir had renal scarring, though it was generally less severe than in patients with a conduit urinary diversion.

[CNS metastases in malignant melanomas].

PURPOSE: To show treatment results and to define prognostic subgroups in patients undergoing radiotherapy for brain metastases from malignant melanoma. PATIENTS AND METHODS: Between 1985 and 1993 30 patients underwent radiation therapy for brain metastases from malignant melanoma. In 9 patients they had been surgically resected. All except 1 patient received whole brain irradiation with a total dose of 20 to 46 Gy/2 to 5 weeks using daily fractions of 2.0 to 4.0 Gy. In 5 patients a local boost of 20 to 25 Gy/2 weeks was administered. Survival rates were compared using the Cox-method. Univariate and multivariate analyses were performed to define prognostic subgroups. RESULTS: In 6/30 patients (20%) brain metastases were diagnosed at the time of primary manifestation of melanoma. In 83% of patients brain metastases developed during the first 5 years following primary diagnosis. Late manifestation was observed (18 years). Overall survival rate of the whole group was 39% at 6 months and 23% at 1 year. Univariate analysis revealed that age at diagnosis of brain metastases, time to manifestation, number of intracranial metastases and existence of extracerebral distant metastases had significant influence on survival. Sex was not found to influence survival rate. Multivariate analysis identified the existence of extracerebral distant metastases at the time of diagnosis of brain metastases as the most important prognostic factor for survival, followed by age and surgical resection. The role of fractionation was studied separately in a subgroup of patients receiving whole brain irradiation to a total dose of 39 to 42 Gy. Survival rates deteriorated when overall treatment time exceeded 3 weeks. CONCLUSION: Prognosis following brain metastases from malignant melanoma is very unfavourable. The described prognostic factors can be helpful to choose the adequate therapeutic modality for the patient, especially for selection of patients for radiosurgery. Whole brain irradiation with 13 x 3 Gy/3 weeks seems a safe and well tolerated treatment schedule either in palliative care or following surgical resection or preceding radiosurgical treatment.

[Does primary tumor affect the prognosis in postmastectomy locoregional recurrence in breast carcinoma?].

BACKGROUND: Prognosis following locoregional recurrence of breast cancer after mastectomy often is described as fatal. However, certain subgroups with better prognosis are supposed. We analysed established prognostic factors for their influence on post recurrence survival in order to discriminate favourable from unfavourable subgroups. PATIENTS AND METHODS: Between 1979 and 1989 163 patients with a local or regional recurrence of breast cancer following mastectomy were treated at the Department of Radiation Oncology of the University of Würzburg. One hundred and forty had an isolated recurrence, without evidence of distant disease at the time of recurrence. Median follow up for patients alive at the time of analysis was 102 months from diagnosis of recurrence. Thirteen prognostic factors were tested. RESULTS: Out of the 140 patients 94 (58%) developed distant metastases within the follow-up period. Metastatic-free rate was 42% at 5 years and 38% at 10 years following recurrence. Recurrences occurred in 50% of patients within the first 2 years from primary surgery, in 83% within 5 years. In univariate analysis statistically significant influence on survival rates was found for pT, pN-status, lymphatic vessel invasion, blood vessel invasion, tumor necrosis, hormonal receptor status, presence or development of distant metastases, time to recurrence and site and extension of recurrence. Two- and 5-year survival rates ranged from 64% to 81% and from 40% to 60%, respectively in the favourable subgroups compared to a survival rate ranging from 15% to 44% at 2 years and 0% to 29% at 5 years in the unfavourable subgroups. In patients with involved axillary lymph nodes, the absolute number of nodes did not prove to have significant influence on overall survival. Histopathological grading did not reach statistical significance levels although an influence on survival was observed. Preceding adjuvant radiotherapy did not influence post-recurrence survival rates. Also preceding adjuvant systemic therapy showed no significant impact on survival. Multivariate analysis demonstrated that primary axillary status correlated most strongly with overall survival (p < 0.001) followed by tumor necrosis (p < 0.01). CONCLUSIONS: The mentioned prognostic factors may be useful in determining the adequate (local and systemic) therapy and the best time for it. Our data support previous findings, that certain subgroups with favourable prognostic features exist and they might still have a chance for cure by an adequate local treatment, whereas subgroups of patients with unfavourable prognostic factors have to receive systemic therapy immediately following local therapy because of the forthcoming systemic progression.

The prognostic significance of the supraclavicular lymph node metastases in breast cancer patients.

PURPOSE: To define the patterns of failure and outcome of patients presenting supraclavicular lymph node involvement and the prognostic significance of supraclavicular lymph node involvement. METHODS AND MATERIALS: We reviewed the history of 795 breast cancer patients treated at the Department of Radiation Therapy, University of Würzburg between 1978 and 1988. The clinical and pathologic features of 21 patients who had ipsilateral supraclavicular lymph node metastases at primary diagnosis and 38 patients who presented supraclavicular lymph node recurrence during the course of disease were reviewed. These were compared with the features of 20 patients who initially had M1 status at primary diagnosis and 278 patients who had developed distant metastases in the follow-up period. Survival rates were calculated starting from the time of diagnosis of supraclavicular involvement respective of distant metastases. RESULTS: Survival from appearance of supraclavicular lymph node metastases at primary diagnosis or as a recurrence is not different from survival of patients presenting with a primary M1 stage or presenting distant metastases during the course of disease. Two and 5-year survival rates of patients with supraclavicular lymph node involvement at primary diagnosis were 52% and 34% compared to 50% and 16% 2- and 5-year survival rate of patients with supraclavicular lymph node involvement as a recurrence. Patients who presented a primary M1-status had 2- and 5-year survival rates of 56% and 24%. Survival of patients with distant metastases calculated from the onset of metastatic disease was similar to that of the other three groups with a 46% and 16% survival rate at 2 and 5 years. There was no difference in survival rates between the four groups. CONCLUSION: The prognostic significance of supraclavicular lymph node involvement at primary diagnosis or as a relapse is similar, both have the same significance as the first distant relapse and are characterized by a poor prognosis.

[The indications for the curative radiotherapy of non-small-cell bronchial carcinoma. Reflections from a clinical viewpoint].

PURPOSE: To find out the indications for treatment and selection criteria of patients who will profit from curative radiotherapy. PATIENTS AND METHODS: A literature review and own data concerning the lymphogenous metastatic pathways and incidence of involvement of loco-regional lymph nodes are used to define the biological treatment volume of a curative irradiation. A retrospective analysis of 266 patients with non-small-cell lung cancer (NSCLC) was performed. The metastatic pathway of the lymphogenous spread was analysed based on pretherapy CT scan as well as clinical examination. RESULTS: Only carefully selected patients under similar selection criteria as for curative surgery are suitable to undergo a curative radiotherapy. The biological treatment volume for curative irradiation has to include the primary with a margin, the ipsilateral hilar nodes as well as the whole mediastinum including the subcarinal lymph nodes, but not the contralateral hilar and supraclavicular lymph nodes. The survival rate of patients with N3 nodal stage are 0%. A 3-step concept for curative radiotherapy until 70 Gy is proposed. CONCLUSIONS: A limited number of patients with NSCLC, carefully selected as for surgery, are suitable to undergo a curative radiotherapy with 70 Gy. This will enable to demonstrate a curative value of radiotherapy.

Prenatal detection of monosomy 21 mosaicism.

We report a case of chromosomal mosaicism for monosomy 21 revealed in amniotic fluid cell culture. Ultrasound examination at 19 weeks' gestation showed in utero growth retardation and a complex cardiac malformation. A repeated amniocentesis confirmed the presence of monosomy 21 mosaicism. In view of the sonographically detected fetal abnormalities, termination of pregnancy was elected.

[Prognostic factors in breast cancer--classification in non-university hospitals].

Prognostic factors in breast cancer have been frequently discussed in the oncologic literature. We reviewed our data of 795 patients who were referred to the Department of Radiation Oncology of the University of Wuerzburg between 1978 and 1988 in order to find out, whether the well known and proven prognostic factors in breast cancer were sufficiently in use in clinical routine, even out of university oncologic centres. We found, that beside of determination of the histological tumor-type the assessment of tumor size (= pT-status) and axillary (= pN-)status is performed nowadays in all patients. In contrary, the determination of the hormonal receptor status (HRS) had a slow beginning. From 1980 the rate of determinated HRS arose from 5% to 80% nowadays. The demand of removal and examination of at least 12 axillary lymph nodes in axillary dissection in order to determine correctly the axillary status is not yet part of the oncological routine. In 1988 in only 40% of the referred patients axillary diagnosis was done in a manner corresponding to international rules.

Percutaneous rotational lithotripsy of gallbladder stones. Clinical results with the Rotolith lithotriptor.

Ten patients (aged 39-94 years) with cholecystolithiasis were selected for percutaneous rotational lithotripsy with the Rotolith lithotriptor either because they were considered high-risk patients for cholecystectomy or because they had refused surgery. The procedure was completed in 7 patients. Five of these were stone-free at cholangiography 1 to 2 days after lithotripsy. Conclusive cholangiograms were not obtained in 2 patients due to gallbladder leakage, which in itself did not cause any serious sequelae. At ultrasonography after one month, one of these 2 patients had no visible gallbladder, the other one had small residual gallbladder stones. Rotational lithotripsy is an alternative to cholecystectomy in patients at high surgical risk, especially elderly patients who have undergone cholecystostomy as an emergency treatment for acute cholecystitis.
