Abstract

Objective Extended curettage with adjuvants of giant cell tumors of bone is associated with a lower rate of recurrence of the tumor while preserving the adjacent joint. The present study was conducted to estimate the recurrence rate and functional outcome after using argon beam as an adjuvant for extended curettage.

Methods We selected 50 patients with giant cell tumors, meeting all the inclusion criteria, who underwent extended curettage using high speed burr and argon beam photocoagulation between July 2016 to January 2019. On their follow-up visit, they were assessed for any complaints of pain and signs like tenderness, locally raised temperature, and decreased range of motion of the adjacent joint. Radiologically, the patients were assessed for any increased lucency around the cement mantle and uptake of the subarticular graft. Musculoskeletal Tumor Society Score (MSTS) was administered to the patients, and range of motion of the adjacent joint was compared with the contralateral joint.

Results Recurrence was found in 4 patients, that is, an 8% recurrence rate. Twenty-six out of 28 patients with a tumor in the lower limb had a grade-5 weight bearing status 6 months from the surgery, and their range of motion was comparable to contralateral healthy joint with an average MSTS score of 27 (18–30).

Conclusion Extended curettage of giant cell tumors using argon beam coagulation is associated with low recurrence rates of the tumor and is an effective modality in the treatment of these tumors besides having a functional outcome comparable to the healthy limb.

Introduction

Giant cell tumor (GCT) of the bone was described by Cooper for the first time in 1818. Thereafter, Nelaton showed their local aggressiveness, and Virchow described their malignant potential. These tumors represent approximately 5% of all primary bone tumors. In most cases, adults between the ages of 20 and 40 years old are affected. It has been observed that this tumor can extend to the articular subchondral bone or even abut the articular cartilage, but the joint and/or its capsule are rarely invaded.[1] The symptoms are generally non-specific, and patients present with local swelling, warmth, and pain radiating independently of weight-bearing. Pathological fracture is seen in about 15% of cases.[2] On x-ray, GCT appears as a pure lytic lesion in the epi-metaphyseal region of the bone; further, the overlying bone may be expanded, and cortical thinning may be seen. Typically, there is a lack of periosteal reaction, except when there is a breach of cortical bone by the tumor.

The treatment of choice in most GCTs is curettage, some adjuvant method, and bone grafting. Simple curettage is seen to have a high rate of recurrence (30–50%). In order to overcome this, different adjuvants have been introduced. These adjuvants, when used with curettage, remove the remainder of the tumor cells because of their thermal (liquid nitrogen, polymethylmethacrylate) or chemical (phenol, hydrogen-peroxide, alcohol) effects.[3]

Argon plasma coagulation (APC) provides hemostasis and tissue coagulation, which uses argon gas to deliver plasma of evenly distributed thermal energy with the help of a probe to a field of tissue adjacent to it. The gas is then ionized by 6,000 volts delivered across the tungsten wire at the tip of the probe. This ionized gas or plasma then seeks a ground in the nearest tissue, delivering the thermal energy with a depth of penetration of roughly 2 to 3.5 mm. Argon gas further has an advantage that it is non-flammable and relatively inexpensive to refill.[4]

The objective of the present study is to assess the rate of recurrence after doing extended curettage of benign aggressive bone tumors in which argon beam was used as an adjuvant to minimize recurrence and improve the postsurgery functional outcome.


#

Methodology

A retrospective observational study of all cases of GCTs of the bone undergoing extended curettage with argon beam coagulation between July 2016 to January 2019 was done. Fifty patients, of both genders, 18 years or older, whose articular surface of the joint adjacent to the tumor was intact on x-ray, were included. The criteria of exclusion were patients with extensive soft-tissue involvement and cortical destruction (breach of > 50% of the area of the cortical bone overlying the tumor), patients with articular surface disruption, and patients younger than 18 years.

All records of the patients, that is, pre and intraoperative findings, old radiographs (x-ray), computed tomography (CT) scan and magnetic resonance imaging (MRI) films were thoroughly checked. Recurrence of tumor was assessed by clinical examination at the time of follow-up, and an X-ray of the operated area was done. Contrast enhanced CT of the chest was done for assessment of metastatic disease.

The surgeries had been performed by the same surgical and anesthetic team, using the same pre and postoperative protocol for all patients. Patients had been operated under general or spinal anesthesia depending on the anesthetist's decision. Incision and soft-tissue dissection had been planned to include the biopsy incision in the incision for the definitive surgery. After thorough curettage and removal of visible tumor tissue, high speed burr was applied to the margins of the cavity, except for the subarticular region, followed by thorough saline wash of the cavity. Once this was done, setting the argon beam machine at 100 watts, argon beam photocoagulation of the cavity walls was performed throughout the cavity ([Figure 1]), including the subarticular region till the bone cavity walls were blackened, keeping that as the end point. Autograft was harvested from the iliac crest and, if required, from the fibula also, taking care to use a fresh set of instruments in order to avoid implanting any tumor cells at the graft site. Fibula cortical struts along with iliac crest graft were used when there was a large cavity involving nearly all of the cross-section of the bone after curettage of the tumor in order to provide greater strength and stability. A bed of the harvested graft was placed in the subarticular region and covered with Gel-Foam. An implant (in most cases, partially threaded 6.5-mm cancellous screws) was fixed to one of the walls of the cavity to anchor the PMMA cement and avoid its dislodgement. The PMMA cement was prepared, and the cavity was filled with the prepared bone cement ([Figure 2]).

The MSTS score was applied to each of these patients on their follow-up visit, depending on the site of involvement along with assessment of range of motion and weight bearing status.

Results

In this series of 50 cases, we found that the average age of the patients was 28.8 years old, with a median age of 26 years old ([Figure 3]). The mean duration of complaints at the time of the first presentation was 6.64 months, with a range of 1 to 18 months. Fourteen patients had the GCT in the distal femur and the proximal tibia each ([Figure 4]). Males were found to be more frequently affected as there were 36 male patients and 14 female patients. The most frequently encountered Campanacci grade was grade 2, with 22 patients being detected at that stage. There were 14 patients presenting with Campanacci grade 1, and 14 patients with Campanacci grade 3. There were 4 patients in whom the tumor had recurred after being treated elsewhere prior to presenting to us. Recurrence of the tumor was found in 4 (8%) patients on the follow-up visit. The average follow-up period was 38 months (range 28–58 months). The average MSTS was found to be 27 at follow-up (range: 18–30) ([Table 1]).

The patients who were treated for lower limb GCTs, returned to full weight bearing ambulation 6 months from the date of surgery. The most common complaint of patients in the postoperative period was pain at the graft site, which was seen in 6 of the 50 patients, 4 patients had superficial surgical site infections, and 4 patients had numbness and tingling in the distal area of the tumor excision ([Table 2]).

Discussion

The treatment modalities for GCT are either wide resection of the tumor with a safe margin, which usually sacrificed the adjacent joint, markedly deteriorating the patient's quality of life or curettage with an adjuvant method.[5]

When compared to other adjuvants, like phenol, argon beam coagulation is not associated with soft-tissue damage due to spillage and is relatively easier to apply to the cavity.[6] Complications, like intraoperative fractures and avascular necrosis of bone, are rarely seen and are associated with cryotherapy using liquid nitrogen as an adjuvant.[7] These advantages in addition to the relatively low recurrence rate make argon beam coagulation a desirable adjuvant modality.

In the current series of 50 patients treated with argon beam as an adjuvant, we found that 4 patients had a recurrence, which was observed on the follow-up visit. The patients underwent re-surgery, curing which an extended curettage of the area of recurrence was done and PMMA was applied in the curetted cavity after treating the area of recurrence with argon beam photocoagulation. This brings the recurrence rate to 8%, which is comparable to the modalities in other published studies ([Table 3]).[8] [9] [10] [11] [12] [13] [14] [15] [16] [17] [18] [19] [20] [21] [22]

We came across 4 patients (8%) who presented to us with recurrence of symptoms after being operated previously. When treated with extended curettage with argon beam, none of them had evidence of recurrence in the follow-up visit.

Four of our patients presented to us with preexisting medical comorbidities. One of the findings was that two patients with diabetes developed superficial surgical site infections. The infections were controlled by intravenous and oral antibiotics, but it prolonged their hospital stay and increased their morbidity. As part of our surgical procedure, placement of the bone graft in the subarticular region to protect the articular cartilage was essential in every case. Bone graft from the iliac crest, fibula, or from both these sites was taken. Graft from only the iliac crest was used in 34 cases (68%), only the fibula was used in 2 patients (4%), and graft from both sites was needed in 14 of our patients (28%). The average duration of hospital stay was 7.76 days, with the maximum duration of hospital stay being 40 days and the minimum being 3 days.

In terms of functional recovery, the MSTS was done for all the patients on follow-up, and the average score was found to be 27 (range 18–30). On examination, it was found that the functional range of motion was maintained in all patients, and they were able to do their activities of daily living. The PMMA cement has its advantages of reducing recurrence and, along with the implant, provide mechanical stability ([Figure 5]). The disadvantage of the cement is that it can lead to articular cartilage damage and further worsen the joint range of motion. In order to avoid this, a thick subarticular graft was given, which separated the articular cartilage from the bone cement. This helped to keep the articular cartilage intact and protect the joint. The subarticular graft was further covered with Gel-Foam in order to avoid any damage to the graft by the thermal effect of the bone cement. Ultimately, an improved range of motion of the joint was seen, which was significant, consistent, and comparable to the joint on the unaffected side ([Figures 6] [7] [8]). This reduced the postoperative rehabilitation time and allowed the patient to resume daily activities soon after the surgery. Subarticular graft uptake was seen on radiographs in all 50 cases which had been taken at 6 months from surgery, and graft resorption was not encountered in this series. In 2018, Wang et al.[23] published a study in which they found that the graft uptake in a curetted cavity ranged from 5 to 9 months. Our study is in agreement with the previous literature.

Six out of 50 patients (12%) complained of pain at the graft site in the immediate postoperative period. The pain subsided in 3 to 5 days with analgesics. Another complaint of the patients was scar marks at the graft site ([Table 3]). None of the patients had severe complaints, such as herniation at the graft site or complaints suggestive of meralgia paraesthetica. Summers B. N. and Eisenstein S. M. conducted a study in 1989 which revealed ‘significant’ donor site pain in 25% of patients, ‘acceptable’ pain in 24%, and no pain in 51% of patients that had bone grafts taken from the iliac crest. The reason for a significantly reduced graft site morbidity was the surgical technique, in which we preferred taking a bicortical iliac crest graft as compared to a tricortical bone graft; besides, we left the inner table of the iliac crest intact and closed the surgical wound in a layered, tension-free manner. Four out of the 50 patients (8%) in our study developed a superficial surgical site infection, which manifested as erythema and induration around the stitch line on the 2nd postoperative day. Intravenous antibiotics along with regular dressings allowed the infection to resolve completely by the 5th postoperative day. All the patients who developed the infections were diabetics. Four (8%) patients in our study complained of tingling and numbness over the distal area of the tumor in the postoperative period. Both these patients were operated for a tumor in the medial condyle of the distal femur. Their complaints had subsided with oral neuromodulators like gabapentin. Takeuchi et al.[24] published a study in 2018 in which they investigated 26 patients with at least 36 months of follow-up and found that osteoarthritis, chronic synovitis, and fracture were observed in one case each (3.8%), which were managed conservatively.

Conclusion

The present study reviewed the data of 50 patients who underwent an extended curettage using argon beam photocoagulation with high-speed burr and PMMA cement. The recurrence rate of the tumor was 8% along with a good functional outcome, since the adjacent joint was not sacrificed. This rate of recurrence was among the lowest in the existing literature. In spite of a small sample size, we can still draw an inference from our study that combining argon beam photocoagulation with extended curettage is an effective modality for the treatment of GCTs and is associated with a significantly reduced rate of recurrence. Its precision, ease of use, and low complication rate make it a valuable adjuvant treatment alternative.
