RESUMO
PURPOSE: We aimed to determine the clinical significance of neck and shoulder pain (NSP) 10 years after posterior spinal fusion (PSF) for thoracic adolescent idiopathic scoliosis (AIS) and the relationship between radiographic parameters and NSP. METHODS: Of 72 patients who underwent PSF for thoracic AIS (Lenke 1 or 2) between 2000 and 2013, we included 52 (46 females; Lenke type 1 in 34 patients and type 2 in 18; mean age, 25.6 years) who underwent NSP evaluation using visual analog scale (VAS, 10 cm) 10 years postoperatively (follow-up rate, 72.2%). Correlation analyses were performed using Spearman's rank correlation coefficient (r). RESULTS: The VAS for NSP was 2.6 cm in median and 3.4 cm in mean at 10 years. The VAS had significant negative correlations with several SRS-22 domain scores (rs = - 0.348 for pain, - 0.347 for function, - 0.308 for mental health, and - 0.372 for total) (p < 0.05). In addition, the VAS score was significantly correlated with cervical lordosis (CL) (rs = 0.296), lumbar lordosis (rs = - 0.299), and sacral slope (rs = 0.362) (p < 0.05). Furthermore, at the 10-year follow-up, CL was significantly negatively correlated with T1 slope (rs = - 0.763) and thoracic kyphosis (TK) (- 0.554 for T1-12 and - 0.344 for T5-12) (p < 0.02). CONCLUSION: NSP was associated with deterioration in SRS-22 scores, indicating that NSP is a clinically significant long-term issue in PSF for thoracic AIS. Restoring or maintaining the TK and T1 slopes, which are controllable factors during PSF, may improve cervical lordosis and alleviate NSP at 10-year follow-up.

BACKGROUND: Fulcrum-bending (FB) correction is considered to provide the best estimation of main thoracic (MT) curve flexibility and postoperative correction in surgical treatment for adolescent idiopathic scoliosis (AIS). However, few studies evaluated the usefulness of FB radiographs for proximal thoracic (PT) curve. We aimed to perform flexibility assessments using both active side-bending (SB) and FB radiographs and evaluate surgical outcomes after posterior spinal fusion (PSF) for Lenke type 2 AIS. METHODS: This study included 38 consecutive patients with Lenke type 2 AIS who underwent PSF using a pedicle screw construct with a minimum 2-year follow-up. Radiographic parameters, including correction rate, SB and FB flexibility, and FB correction index (FBCI: [correction rate/FB flexibility] × 100), were evaluated preoperatively, immediately after surgery, and at the 2-year follow-up. The clinical outcomes were preoperatively evaluated using the Scoliosis Research Outcomes Instrument-22 and at the follow-up. RESULTS: All scoliosis curves significantly improved and shoulder balance shifted toward left shoulder elevation (all comparisons, p < 0.0001). There were significant differences between the SB and FB corrections in the PT and MT curves (p < 0.0001). The magnitudes of the discrepancies between the SB and FB corrections in the PT and MT curves were 11.2° ± 5.2° and 11.6° ± 7.2°, respectively. FB correction did not differ from postoperative Cobb angles correction immediately after surgery or at the 2-year follow-up; the mean FBCIs in the PT and MT curves were 98.8% and 105.5%, respectively. The self-image domain SRS-22 scores had significantly increased at the 2-year follow-up (p < 0.0001). CONCLUSIONS: There were significant differences between the SB and FB corrections, and FB correction tended to approximate the postoperative curve correction (FBCI = 100%) for PT and MT curves in patients with Lenke type 2 AIS. FB flexibility is more reliable than SB flexibility in evaluating actual curve flexibility even for the PT curve.

BACKGROUND: Although skeletal maturity and brace wear time contribute to the success of brace treatment in adolescent idiopathic scoliosis (AIS), the extent of initial in-brace correction for ensuring successful outcomes remains unclear. We hypothesized that the degree of initial in-brace correction correlates with brace success in patients with AIS. METHOD: The study included 135 AIS patients with a major Cobb angle of 20°-40° treated with a thoracic lumbosacral orthosis for at least one year and followed up for skeletal maturity. The subjects were divided into two groups: the skeletally immature group (group I, n = 72), who met the Bracing in Adolescent Idiopathic Scoliosis Trial study protocol at the start of brace treatment, and the skeletally mature group (group M, n = 63). Treatment success was defined as not needing surgical treatment and a major Cobb angle <40° at the end of brace treatment. RESULTS: In both groups, the mean major Cobb angles before treatment, while wearing the brace, and at the end of brace treatment were 30.6°/31.7°, 22.9°/24.2°, and 38.8°/33.9° (p < 0.05), respectively, and the treatment success rate was 56.9% and 77.8%, respectively (p < 0.05). Univariate regression analysis revealed the following risk factors: Risser grade 0 in group I, major Cobb angles before treatment, initial in-brace major Cobb angle, and in-brace correction rate in both groups. Cutoff values of in-brace major Cobb angle for treatment success calculated by ROC curve in groups I and M were 24° and 29°, respectively. CONCLUSIONS: In-brace major scoliosis correction of <25° in patients with immature skeletal status and <30° in patients with mature skeletal structure should be aimed at to achieve significant brace treatment success.

BACKGROUND: Previous studies have demonstrated that the point prevalence of back pain ranges from 12 % to 33 % and that the lifetime prevalence of back pain ranges from 28 % to 51 % in adolescents. However, few studies on back pain in patients with Adolescent idiopathic scoliosis (AIS) have been conducted, and these studies had significant limitations, including a lack of comparative controls and detailed information about scoliotic deformity or pain location. This study aimed to determine whether adolescents with AIS experience back pain in specific regions. METHODS: This retrospective case-control study included 189 female adolescents with AIS who underwent corrective fusion from 2008 to 2020. Questionnaires on back pain and health-related quality of life (HRQOL) using the Scoliosis Research Society Outcomes Instrument-22 (SRS-22) were conducted preoperatively. The control group included 2909 general female adolescents. RESULTS: The mean Cobb angles in the main thoracic and thoracolumbar/lumbar curves were 51.4 ± 15.3° and 40.4 ± 12.9°. Back pain characteristics included higher point prevalence (25.9 %) and lifetime prevalence (64.6 %) compared to healthy controls. Adolescents with back pain showed lower scores in the pain and mental health domains of the SRS-22. Adolescents with major thoracic AIS showed more back pain in the upper and middle right back compared to adolescents with major thoracolumbar/lumbar AIS. CONCLUSION: The point and lifetime prevalence of back pain were definitely higher in patients with AIS, which affected their HRQOL. There was a relationship between pain around the right scapula and the right major thoracic curve with a rib hump deformity.
RESUMO
BACKGROUND: Intraoperative pathological diagnosis has a major influence on the intra- and postoperative management of spinal cord tumors. Thus, the aim of this study was to assess the reliability of intraoperative pathological diagnosis for spinal cord lesions by comparing it with the final pathological diagnosis and to determine its usefulness and limitations. METHOD: Three-hundred and three consecutive patients (mean age, 53.9 years) with neoplastic spinal cord lesions who underwent initial surgery between 2000 and 2021 were included. The anatomical locations of the spinal cord tumors and the implementation rate of intraoperative pathological diagnosis in each tumor type were evaluated. As the primary outcome, we determined the concordance rates between the intraoperative pathological diagnosis and the final diagnosis. When the intraoperative pathological diagnosis and final diagnosis were the same, the diagnosis was defined as a "match." Otherwise, the diagnosis was defined as a "mismatch." RESULTS: The overall implementation rate of intraoperative pathological diagnosis was 53%, with implementation rates of 71%, 45%, 47%, and 50% for intramedullary, intradural extramedullary, extradural, and dumbbell tumors, respectively. The overall concordance rate was 87.6%, with concordance rates of 80%, 95%, 75%, and 90% for intramedullary, intradural extramedullary, extradural, and dumbbell tumors, respectively (p < 0.05). The diagnoses of ependymomas, low-grade astrocytomas, and high-grade astrocytomas was occasionally difficult among intramedullary tumors. Among intradural extramedullary tumors, differentiation between grade 1 meningioma and high-grade meningioma was difficult using intraoperative pathological diagnosis. CONCLUSIONS: Surgeons must recognize the lower accuracy of intraoperative pathological diagnosis for intramedullary and extradural lesions and make a final decision by considering the intraoperative gross findings, preoperative clinical course, and imaging.
RESUMO
PURPOSE: It has been reported that C7 and C8 nerve root impairment can cause drop finger; however, the clinical characteristics of each injured nerve root and post-operative outcomes remain unclear. This study aimed to investigate the detailed features and surgery-related prognostic factors of drop finger caused by cervical radiculopathy. METHODS: We retrospectively investigated the clinical characteristics, paralysis patterns and surgery-related prognostic factors of 23 patients with drop finger caused by cervical radiculopathy who underwent posterior cervical foraminotomy. We classified paralysis into three patterns based on the fingers predominantly exhibiting extensor digitorum communis (EDC) muscle weakness: index finger side-dominant, middle and ring fingers-dominant and little finger side-dominant. RESULTS: The aetiologies were cervical disc hernia (CDH) in ten patients, cervical spondylotic radiculopathy (CSR) in eight and both CDH and CSR in five. The levels of the decompressed root were C7 in one patient, C8 in 11 and both C7 and C8 in 11. Scapular pain was frequently observed as the initial symptom (78%), especially in patients with only C8 nerve root disorder (91%). Drop finger recovered to a score of ≥ 3 on manual muscle testing in 17 patients; patients with the little finger side-dominant pattern tended to have poor recoveries. Patients with CDH improved significantly than those with CSR or both CDH and CSR (p < 0.05). CONCLUSIONS: Good surgical recovery of drop finger can be expected in patients with CDH and in those with index fingers-dominant and middle and ring fingers-dominant patterns.

The aim of this study was to survey the incidence of osteoporotic fragility fractures, which include vertebral, hip, distal radius, and proximal humerus fractures, in patients ≥ 50 years of age, from 2004 to 2015, in Sado City, Japan. We examined temporal changes in the incidence of these fractures from 2010 through 2015. The incidence of vertebral (p < 0.001) and radius fractures (p = 0.001) was lower in 2015 than in 2010, with only the incidence of hip fracture (p = 0.013) being lower in 2015 than in 2004. With regard to age-specific incidences, there was a sharp increase in vertebral and hip fractures among the segment of the population 70-89 years old, with no remarkable change in the incidence of radial and humeral fractures. Pre-existing vertebral fractures were identified in 69.6% of patients with a hip fracture, 35.6% of patients with a distal radius fracture, and 55% of patients with a humeral fracture. Among patients with pre-existing vertebral fractures, 42.5% had a single fracture, whereas 57.5% had 2 or more fractures. The proportion of patients on anti-osteoporotic agents before the occurrence of fractures increased to 14.5% in 2015, compared to 4% in 2004 and 7.6% in 2010. We speculate that the increase in the use of anti-osteoporotic agents is the main reason for the declining incidence of fractures. Therefore, considering the sharp increase in hip and vertebral fractures among individuals in their mid-1970s and older, judicious use of anti-osteoporotic agents among these individuals could be useful for lowering the occurrence of these fractures.

Background and objectives Mixed reality (MR) is one of the image processing technologies that allows the user to manipulate three-dimensional (3D) virtual images (hologram). The aim of this study was to evaluate the accuracy of MR-based pedicle screw (PS) placement using 3D spine models. Materials and methods Using the preoperative CT data of a patient with adolescent idiopathic scoliosis (AIS) who had undergone posterior spinal fusion in our hospital, a 3D-printed spine model was created. On the other hand, a 3D hologram of the same patient was automatically created using the preoperative CT data uploaded to the Holoeyes MD service website (Holoeyes Inc., Tokyo, Japan). Using a Magic Leap One® headset (Magic Leap Inc., Plantation, FL), the 3D hologram with lines of predetermined PS trajectories was superimposed onto the 3D-printed spine model and PS were inserted bilaterally along with the trajectory lines from T5 to L3. As a control, we used a readymade 3D spine model of AIS and inserted PS bilaterally with a freehand technique from T4 to L3. The rate of pedicle violation was compared between the MR-based and freehand techniques. Results A total of 22 and 24 PS were placed into the 3D-printed spine model of our patient and the readymade 3D spine model, respectively. The rate of pedicle violation was 4.5% (1/22 screws) in the MR-based technique and 29.2% (7/24 screws) in the freehand technique (P = 0.049). Conclusions We demonstrated a significantly lower rate of PS misplacement in the MR-based technique than in the freehand technique. Therefore, an MR-assisted system is a promising tool for PS placement in terms of feasibility, safety, and accuracy, warranting further studies including cadaveric and clinical studies.
RESUMO
Introduction: In this study, we aim to estimate the natural standing sagittal alignment in patients with adult spinal deformity (ASD), firstly by investigating the normative values of anatomical pelvic parameters based on the anterior pelvic plane (APP) in a healthy population, and to clarify the relationships between the anatomical and positional pelvic parameters in standing position. Methods: The images of biplanar slot-scanning full-body stereoradiography in 140 healthy Japanese volunteers (mean age, 39.5 years; 59.3% female) were examined. In addition to three-dimensional measurements including pelvic incidence (PI), sacral slope (SS), and pelvic tilt (PT), the APP angle (APPA; anterior tilting=positive) was measured as the angle between the APP and the vertical line using the two-dimensional lateral image. Anatomical SS and PT (aSS and aPT) were calculated as the angles of SS and PT in reference to APP. Results: The mean (range) values of APPA, aSS, and aPT were determined to be 0.7° (-16.8°/15.5°), 36.8° (18.3°/64.9°), and 13.2° (-0.6°/28.7°), respectively. Moreover, SS was found to be significantly correlated with PI and aSS, while PT was significantly correlated with PI, aSS, aPT, and body weight. Also, PT was significantly larger in females than in males. Multiple linear regression analysis deduced the following equations: SS=0.404×aSS+0.203×PI+12.463, PT=-0.391×aSS+0.774×PI+1.950×sex (male=0, female=1)-12.971, wherein aSS had the greatest effect for predicting SS among the included factors and PI had the greatest effect for predicting PT. In addition, no significant differences were noted between PT/PI and aPT/PI. Conclusions: As per the results of this study, significant correlations were noted among parameters and predicting models for positional parameters (SS and PT) using anatomical parameters (aSS and aPT) in a healthy population. This novel measurement concept based on the APP has been considered to be useful in estimating natural SS and PT in standing position using the anatomical pelvic parameters in patients with ASD.
RESUMO
INTRODUCTION: Although multimodal intraoperative neuromonitoring (IONM), which has high sensitivity and specificity, is typically performed during spinal deformity surgery, neurological status may deteriorate with delay after surgical maneuvers. Here, we report a rare case of delayed postoperative neurological deficit (DPND) that was not detected by IONM during posterior spinal fusion (PSF) for congenital scoliosis. CASE PRESENTATION: A 14-year-old male presented with congenital scoliosis associated with T3 and T10 hemivertebrae. Preoperative Cobb angle of proximal thoracic (PT) and main thoracic (MT) curves were 50° and 41°, respectively. PSF (T1-L1) without hemivertebrectomy was performed, and the curves were corrected to 31° and 21° in the PT and MT curves, respectively, without any abnormal findings in IONM, blood pressure, or hemoglobin level. However, postoperative neurological examination revealed complete loss of motor function. A revision surgery, release of the curve correction by removing the rods, was immediately performed and muscle strength completely recovered on the first postoperative day. Five days postoperatively, PSF was achieved with less curve correction (36° in the PT curve and 26° in the MT curve), without postoperative neurological deficits. DISCUSSION: Possible mechanisms of DPND in our patient are spinal cord ischemia due to spinal cord traction caused by scoliosis correction and spinal cord kinking by the pedicle at the concave side. Understanding the possible mechanisms of intra- and postoperative neural injury is essential for appropriate intervention in each situation. Additionally, IONM should be continued to at least skin closure to detect DPND observed in our patient.

STUDY DESIGN: A retrospective cohort study using prospectively collected data. OBJECTIVES: To investigate the incidence and impact of fusion to the upper thoracic spine on neck-shoulder symptoms after posterior spinal fusion (PSF) for adolescent idiopathic scoliosis (AIS). SUMMARY OF BACKGROUND DATA: Axial neck-shoulder pain is established as a sequela of posterior cervical spine surgery and is mainly caused by the dissection of extensor muscles in the cervical and upper thoracic spine. MATERIALS AND METHODS: Sixty-three female patients with AIS who underwent PSF using segmental pedicle screw constructs for structural main thoracic curve with a minimum 2-year follow-up were included. Axial neck-shoulder pain was assessed using the visual analog scale and cervical spine function domain score of the Japanese Orthopedic Association Cervical Myelopathy Evaluation Questionnaire. The patients were divided into 2 groups, a higher group (underwent fusion up to T3 or above, n=27) and a lower group (underwent fusion up to T4 or below, n=36), and radiologic and clinical outcomes were compared. RESULTS: The incidence of axial neck-shoulder pain (visual analog scale ≥30) preoperatively and at the 2-year follow-up was 29 and 40%, respectively. The pain and mental health domains of the Scoliosis Research Society-22 and cervical spine function domain of the Japanese Orthopedic Association Cervical Myelopathy Evaluation Questionnaire were correlated with the severity of axial neck pain. In the comparison of clinical outcomes between the 2 groups, the pain domain score of the Scoliosis Research Society-22 in the lower group was significantly better than that in the higher group at the 2-year follow-up ( P <0.05). Other parameters showed no significant differences preoperatively or at the 2-year follow-up. CONCLUSION: Female patients with AIS had a relatively high incidence of axial neck-shoulder pain after PSF, which affected their health-related quality of life. Both groups showed similar clinical outcomes, and the cranial fusion level did not affect axial neck-shoulder pain and cervical spine function. LEVEL OF EVIDENCE: Level 3.

PURPOSE: We aimed to investigate the marital status and childbirth in adolescent idiopathic scoliosis (AIS) patients. METHODS: This study included women who were treated surgically or non-surgically for AIS with a scoliosis magnitude ≥ 30° before surgery or at skeletal maturity and were followed up until age 30 years or older. Patients were divided into surgically treated (S-AIS, n = 55) and non-surgically treated AIS groups (N-AIS, n = 86). Data from the national fertility survey were used as control values. RESULTS: There were no significant differences in age at the final follow-up between the S- (40.7 years) and N-AIS (42.1 years) groups. The unmarried rate among all women and the nulliparous rate among married women in the S-AIS group (29.1% and 18.4%, respectively) were similar to those in the N-AIS group (26.7% and 16.1%, respectively). The mean number of children per married woman also did not differ between the S- and N-AIS groups (1.5 vs 1.4). Compared to the control group, after adjusting for age, the common odds ratio in the AIS group was 1.56 (p = 0.031) for unmarried status and 1.88 (p = 0.026) for nulliparity among married women. Moreover, the mean number of children per married woman was significantly lower in the AIS group than in the control group (1.3 vs 1.7, p < 0.001). CONCLUSION: Surgically and non-surgically treated women with AIS had a similar status with regard to marriage and childbirth, while women with AIS were more likely to be unmarried and nulliparous and to have fewer children compared to the nationwide population.

Introduction: Gait disturbance due to compressive cervical myelopathy has been previously described. However, data on how gait disturbance varies with the degree of lower extremity motor impairment are limited. Therefore, we investigated the characteristics of gait analysis based on severity and determined how gait disturbance progresses in compressive cervical myelopathy. Methods: We enrolled 44 patients (32 men and 12 women; mean age, 65.0 years) out of 108 consecutive patients with compressive cervical myelopathy who underwent spinal cord decompression surgery in our hospital. The exclusion criteria were inability to gait and complications affecting gait. Twenty-two patients with Japanese Orthopaedic Association scores 1 or 2 for lower extremity motor functions were assigned to the severe group, and 22 patients who scored 3 or 4 were assigned to the moderate group. Gait analysis was performed preoperatively using a long thin-type sensor sheet, and 25 healthy volunteers were assigned to the control group. Results: Stride length, swing phase, and gait speed decreased whereas step angle, stance phase, and double support duration increased as myelopathy progressed. Step width was significantly larger in the severe group than in the moderate and control groups. The cutoff values based on severe myelopathy with the inability to ascend or descend stairs without support were 60% for the stride length percentage of body height and 100 cm/s for gait speed. Conclusions: Decreases in stride length, swing phase, and gait speed and increases in step angle, stance phase, and double support duration are compensatory changes as cervical myelopathy progresses. Step width is a compensatory change that is not significantly altered in moderate myelopathy but increases when gait becomes affected, such that the patient cannot ascend or descend stairs without support.
RESUMO
Teriparatide (TPTD) administration has a potent osteogenic action and promotes the healing of osteoporotic vertebral fractures (OVFs). We aimed to investigate the outcomes of vertebroplasty with posterior spinal fusion (VP + PSF) and determine the impact of perioperative TPTD administration. We included 73 patients (18 male and 55 female patients; mean age: 78 years) with thoracolumbar OVFs who underwent VP + PSF and were followed-up for at least 2 years. Twenty-three patients who received TPTD perioperatively for > 3 months were included in the TPTD group, and the remaining 50 patients were included in the non-TPTD group. Radiographic findings regarding sagittal alignment and clinical outcomes in both groups were compared. The mean duration of TPTD administration was 17.5 ± 5.0 months (range 4-24 months). The mean loss of correction of local kyphosis angle in the TPTD group (4.0°) was lesser than that in the non-TPTD group (7.5°; p < 0.05); however, no significant differences were observed between the groups regarding global sagittal alignment, the occurrence of subsequent vertebral fractures, pedicle screw loosening and treatment-efficacy rates of clinical outcomes. Local kyphosis correction in patients who underwent VP + PSF for OVFs could be maintained through perioperative TPTD administration; however, TPTD administration had little effect on clinical outcomes.

A 52-year-old woman visited our hospital with epigastralgia. Detailed examination revealed a duodenal cancer of the ascending limbs. Since she refused the resection, the administration of S-1 alone was commenced. After one course of this treatment, oral intake became impossible. Duodenography and endoscopy showed duodenal obstruction, and she underwent surgery. The tumor proved to be unresectable due to direct invasion of the inferior vena cava. Duodenojejunostomy was performed. After surgery, she was treated by S-1 and survived 2 years and 11 months, which resulted in 3 years and 2 months' long survival from her first visit. The intervals of the intake and home stay, after the operation, were 2 years and 8 months and 2 years and 5 months, respectively. The combination of S-1 administration and bypass operation provides a useful alternative for the treatment of unresectable duodenal cancer with stenosis.

PURPOSE: The recovery rate of Japanese Orthopedic Association (JOA) score with K-line (-) cervical ossification of the posterior longitudinal ligament (OPLL) for posterior decompression with in-situ fusion (PDF) tends to be lower than that of anterior decompression with fusion (ADF). However, ADF is a technically demanding operation and has ADF-specific complications. This prospective report introduced a novel concept of PDF with selective lordotic correction as well as prophylactic foraminal decompression. METHODS: Six consecutive patients (four men and two women; mean age, 61.8â¯years) were included. PDF was performed, attempting to create cervical lordosis to acquire a posterior shift of the spinal cord, while preventing postoperative C5 palsy by prophylactic facetectomy and selective lordotic correction. RESULTS: The mean recovery rate of JOA score at the final follow-up was 70.9⯱â¯20.3%. The mean C2-C7 angle preoperatively and at final follow-up was 5.5⯱â¯3.9° and 12.2⯱â¯4.8°, respectively. No symptomatic nerve root palsy, except one case with transient C7 root iatrogenic palsy, was found. CONCLUSIONS: A novel concept of PDF with selective lordotic correction obtained recovery rates of JOA scores comparable to those of ADF. We believe that this method can improve PDF outcomes in patients with K-line (-) OPLL.

In cases with advanced/recurrent gastric cancer undergoing single therapy with TS-1, we retrospectively discussed the antitumor effects and adverse events and considered the clinical utility of TS-1. The subjects consisted of 131 cases with advanced/recurrent gastric cancer who received one or more courses of therapy with TS-1 alone between July 1999 and August 2003. We carried out 4-week administration of 80-120 mg/day of TS-1 according to body surface area, followed by a 2-week discontinuation, then repeated administration which adjusting the dosage according to the incidence of side effects, and discussed the antitumor effects and adverse events. The response rate in all cases was 21% and the median survival time (MST) was 343 days, or 25.3% and 265 days if limited to unresectable and recurrent cases. The response rates were 38.2% for unresectable cases, 16.3% for recurrent cases and 14.6% for curability C cases, and the MSTs were 250 days, 276 days and 419 days, respectively. The response rates in terms of whether or not patients had received chemotherapy were 11.6% for those who had received chemotherapy and 40.0% for those who had not, and the MSTs were 239 days and 325 days, respectively. Thus, both were significantly better in patients who had not received chemotherapy. The response rates for patients who had not received chemical therapy by target organs were favorable on the order of 50% for stomach and 33% for liver metastasis, and the MSTs were on the order of 474 days for peritoneum, 39 1 days for liver metastasis and 326 days for lymph nodes. There were 10 cases of long-term survival of 600 days or longer, but not in unresectable cases, and the target organs in many of the cases were the peritoneum and lymph nodes. Adverse reactions were observed in 34.4% of all cases and those of grade 3 or more in 9.4%, all of which were improved only by discontinuation of the drug. It was again confirmed that single therapy with TS-1 for advanced/recurrent gastric cancer is an excellent therapy providing both high antitumor effects and safety.

The aim of this study was to evaluate the efficacy and toxicity of 5-fluorouracil (5-FU) and l-leucovorin (l-LV) given at the same dose intensity and administered monthly (given weekly for 3 weeks followed by a week of rest; arm A) or every 2 months (given weekly for 6 weeks followed by 2 weeks rest; arm B) to patients with advanced colorectal carcinoma. The dose of 5-FU was 500 mg/body or 750 mg/body, with an average dose of 432.8 mg/m2. A total of 7 institutions participated in this multi-center study and were randomly divided into 2 groups of arms A and B. Thirty-three patients were entered into arm A and 21 into B. The overall response rate was significantly (p = 0.007) greater in arm B (23.5%) than in arm A (0%). The most frequently observed toxicity was diarrhea, which was observed in 6.5% of arm A and in 33.3% of arm B, marking a significant difference (p = 0.034). These data suggest that a monthly 5-FU/l-LV regimen might be less toxic than a 2-months regimen and less effective at the dose given as above. Further study is needed to evaluate the efficacy of a monthly regimen.
